Description

    FIELD OF THE INVENTION
  • The present invention relates to a metal plate on which surface processing has been performed, a storage case in which the metal plate is used, and a method for processing a surface of the metal plate.
    • BACKGROUND OF THE INVENTION
  • Metal plates are sometimes used for panels that constitute a front surface and side surfaces of a storage case provided in a kitchen or the like. Because a user tends to see the front surface and the side surfaces of the storage case, and the front surface and the side surfaces need high aesthetics and a good design, surface processing is sometimes performed on the metal plates used for the front surfaces and the side surfaces. In Patent Document 1, for example, a method for forming polishing pattern columns on a surface of a stainless steel sheet by pressing a polishing grindstone against the stainless steel sheet that serves as a metal plate while the polishing grindstone is rotated, and moving the stainless steel sheet relative to the polishing grindstone is disclosed as a method for processing a surface of a metal plate.
    • RELATED DOCUMENTS PATENT DOCUMENTS
  • Patent Document 1: JP S60-67060A
    • SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION
  • According to the method of Patent Document 1 above, a surface of the stainless steel sheet can be provided with a better design by processing the surface of the stainless steel sheet, compared to a case where the surface of the stainless steel sheet is not processed. However, the method of Patent Document 1 provides a simple pattern in which a plurality of polishing marks that head in a predetermined direction are simply lined up. Thus, it is desirable to develop a method for processing a surface with which higher aesthetics and better design can be provided.
  • In the light of such issues, an object of the present invention is to provide a metal plate provided with higher aesthetics and better design, a storage case in which the metal plate is used, and a method for processing a surface of a metal plate with which higher aesthetics and better design can be provided to the metal plate.

  • In order to resolve the above-described issues, in a representative configuration of a metal plate according to the present invention, on a surface of the metal plate, a plurality of first polishing columns are formed in parallel to each other, with multiple circular arc-shaped polishing marks being successively formed in a direction in which the circular arcs curve, and a plurality of second polishing columns are formed in parallel to each other, with multiple circular arc-shaped polishing marks being successively formed, as in the first polishing columns, the second polishing columns intersecting with and superimposed on the first polishing columns.
  • According to the above-described configuration, a grid-shaped pattern constituted by the first polishing columns and the second polishing columns that intersect with and are superimposed on each other is formed on the surface of the metal plate. At this time, a spatial effect (sense of depth) is achieved due to the fact that the circular arc-shaped polishing marks constituting the first polishing columns and the second polishing columns intersect with and are superimposed, and the grid-shaped pattern just like rises. Accordingly, the surface of the metal plate can be provided with higher aesthetics and better design.
  • The above-described first polishing columns and second polishing columns may be arranged such that directions in which circular arcs of adjacent polishing columns curve are alternately opposite to each other. With this configuration, the border of adjacent first polishing columns, the border of adjacent second polishing columns, and the outline of the grid-shaped pattern are conspicuous, and thus the above-described effect can be more improved.
  • In order to resolve the above-described issues, in another configuration of a metal plate according to the present invention, on a surface of the metal plate, a polishing pattern in which a plurality of polishing columns are arranged in parallel to each other is formed by multiple superimposition of polishing patterns in different directions, the polishing columns being formed by successively forming multiple circular arc-shaped polishing marks linearly or arcuately. With this configuration as well, a similar effect to that of the above-described metal plate can be obtained.
  • In the metal plate, the shape of the polishing columns may differ for each polishing pattern. Also, the polishing columns may be arranged such that directions in which circular arcs of adjacent polishing columns curve are alternately opposite to each other. Accordingly, the above-described effect can be improved.
  • In order to resolve the above-described issues, in a representative configuration of a storage case according to the present invention, the metal plate is used for a panel of a front surface or a side surface. Usage of the above-described metal plate makes it possible to provide the storage case with higher aesthetics and better design.
  • In order to resolve the above-described issues, in a representative configuration of a method for processing a surface of a metal plate according to the present invention, on a surface of a metal plate, a plurality of first polishing columns are formed in parallel to each other, with multiple circular arc-shaped polishing marks being successively formed in a direction in which the circular arcs curve, by polishing the surface of the metal plate while moving a rotary polishing tool, and a plurality of second polishing columns are formed in parallel to each other, with multiple circular arc-shaped polishing marks being successively formed, as in the first polishing columns, the second polishing columns intersecting with and superimposed on the first polishing columns.

Constituting elements and their description corresponding to an embodiment of the above-described metal plate are also applicable to a method for processing a surface of the metal plate.
  • In order to resolve the above-described issues, in another configuration of the method for processing a surface of a metal plate according to the present invention, on a surface of a metal plate, a polishing pattern in which a plurality of polishing columns are arranged in parallel to each other is formed by multiple superimposition of polishing patterns in different directions, the polishing columns being formed by successively forming multiple circular arc-shaped polishing marks linearly or arcuately by polishing the surface of the metal plate while moving a rotary polishing tool. Also, the polishing columns may be formed such that directions of adjacent polishing columns are alternately opposite to each other. With this configuration as well, a similar effect to that of the above-described method for processing a surface of a metal plate can be obtained.
  • The metal plate may be a stainless steel sheet. Use of a stainless steel sheet as the metal plate in this manner makes it possible to achieve high strength and rust prevention, in addition to high aesthetics and good design.

    Embodiments of the Invention
  • Preferable embodiments of the present invention will be described in detail with reference to the attached drawings. The dimensions, materials, and any other specific values or the like described in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise stated. Note that in the present specification and drawings, elements having substantially the same functions and configurations will be assigned the same reference numerals to omit redundant descriptions, and elements that are not directly related to the present invention will be omitted in the drawings.
  • FIG. 1 is a representative diagram showing a storage case 100 including a metal plate 110 according to the present embodiment. Note that although the case where the metal plate 110 is disposed on a front plate 102 constituting a front surface of the storage case 100 (drawer) shown in FIG. 1 is described as an example in the present embodiment, the present invention is not limited to this, and the metal plate 110 of the present embodiment can be used for another article other than the storage case 100. The metal plate 110 of the present embodiment can be used in a metal portion such as a side plate, a front plate that is not the drawer, a sliding door, or a top board of the storage case 100, for example.
  • The storage case 100 shown in FIG. 1 is a drawer that is accommodated in a cabinet (not shown) and accommodates articles (not shown). The storage case 100 includes a front plate 102 constituting a front surface, two side plates 104a, 104b constituting side surfaces, a bottom plate 106 constituting a bottom surface, and a back plate 108 constituting a back surface. The metal plate 110 is disposed on the front side of the front plate 102.
  • FIGS. 2 and 3 are diagrams illustrating a method for processing the surface of the metal plate 110 shown in FIG. 1. Hereinafter, the metal plate 110 on which surface processing has been performed with the surface processing method will also be described together with a detailed description of the surface processing method. Note that in order to facilitate the understanding, first polishing columns 112 shown in FIG. 2(c) are indicated with broken lines in FIGS. 3(a) to 3(c).
  • As shown in FIG. 2(a), in the present embodiment, a surface 110a of the metal plate 110 is polished while the rotary polishing tool 120 is moved. When the surface 110a of the metal plate 110 is polished by moving the rotary polishing tool 120 while rotating in a direction of the arrow shown in FIG. 2(a), as shown in FIG. 2(b), a first polishing column 112 is formed on the surface 110a of the metal plate 110, with multiple circular arc-shaped polishing marks being successively formed in a direction in which the circular arcs curve. The surface 110a of the metal plate 110 takes on a state shown in FIG. 2(c) due to the formation of a plurality of these first polishing columns 112 in parallel to each other on the surface 110a of the metal plate 110.
  • Subsequently, second polishing columns are formed that intersect with the first polishing columns 112. Specifically, the surface 110a of the metal plate 110 on which the plurality of first polishing columns 112 are formed in parallel to each other, which is shown in FIG. 2(c), is moved in a direction of the arrow shown in FIG. 3(a), that is, the second polishing columns intersect with the first polishing columns 112 (in a direction orthogonal to the direction of the first polishing columns 112), while the rotary polishing tool 120 is rotated, and thereby the surface 110a is polished. Accordingly, as shown in FIG. 3(b), a second polishing column 114 is formed on the surface 110a of the metal plate 110, with multiple circular arc-shaped polishing marks being successively formed, as in the first polishing columns 112, the second polishing column 114 intersecting with and superimposed on the first polishing columns 112. The surface 110a of the metal plate 110 takes on a state shown in FIG. 3(c) due to the formation of a plurality of these second polishing columns 114 in parallel to each other on the surface 110a of the metal plate 110.
  • As shown in FIG. 3(c), on the surface 110a of the metal plate 110 on which surface processing has been performed with the surface processing method of the present embodiment, the plurality of first polishing columns 112, with multiple circular arc-shaped polishing marks being successively formed in a direction in which the circular arcs curve, and the plurality of second polishing columns 114, with multiple circular arc-shaped polishing marks being successively formed, intersecting with and superimposed on the first polishing columns 112, are formed in parallel to each other.
  • When light is reflected by one polishing column, light is reflected well at portions in which a polishing mark is orthogonal to the line of sight and serves as a bright spot, and only little light is reflected at portions in which a polishing mark forms a sharp angle with the line of sight. Thus, bright spots are formed successively along a polishing column, forming a bright stripe. The stripe of bright spots is repeatedly formed due to the polishing columns being arranged in parallel to each other.
  • Moreover, bright spots in circular arcs can be perceived by right and left eyes at different positions due to the fact that the first polishing columns 112 and the second polishing columns 114 intersect with and are superimposed on each other. The polishing columns being located at different positions in this manner causes a difference in the positions at which the bright spots are perceived, a viewer perceives a spatial effect (sense of depth). Therefore, a grid-shaped pattern of the first polishing columns 112 and the second polishing columns 114 can be perceived as if they rise, the surface 110a of the metal plate 110 can be provided with higher aesthetics and better design, and the aesthetics and design of the storage case 100 can be improved.
  • FIG. 4 is a diagram illustrating a polishing direction in the surface polishing method of the present embodiment. In the example described with reference to FIGS. 2 and 3, as shown in FIG. 4(a), in the plurality of first polishing columns 112 formed in parallel to each other, the directions in which the circular arcs of adjacent polishing columns curve, that is, the directions in which the rotary polishing tool 120 advances are all the same (namely, the direction in which the circular arcs head from right to left in FIG. 4(a)). Similarly, in the plurality of second polishing columns 114 formed in parallel to each other, the directions in which the circular arcs of adjacent polishing columns curve, that is, the directions in which the rotary polishing tool 120 advances are all the same (namely, the direction in which the circular arcs head from top to bottom in FIG. 4(a)).
  • In contrast to the above, in the example shown in FIG. 4(b), when the plurality of first polishing columns 112 and the plurality of second polishing columns 114 are formed, the directions in which the rotary polishing tool 120 advances are alternately opposite to each other, that is, the directions are reversed at every single column. Accordingly, as shown in FIG. 4(c), the circular arcs of the adjacent first polishing columns 112 and adjacent second polishing columns 114 that have been formed are curved in opposite directions.
  • Because the directions in which the circular arcs curve are alternately opposite to each other, columns in which portions orthogonal to the line of sight protrude (are convex) and columns in which portions orthogonal to the line of sight are recessed (concave) are alternately arranged. A thick and intensively bright stripe forms in the recessed (concave) columns, and a thin and weakly bright stripe forms in the protruding (convex) columns. The thick and intensively bright stripe is perceived as being close, and the thin and weakly bright stripe is perceived as being distant. Also, when the angle of the line of sight is changed (when the position of the viewer's face is changed), many positions at which light is reflected change in the recessed columns in, and only few positions change in the protruding columns. Therefore, the metal plate is perceived as if it has a surface having two layers, and the spatial effect (sense of depth) can be further improved. Moreover, the metal plate is perceived as if it has a surface having four layers due to the superimposition of the first polishing columns 112 and the second polishing columns 114 intersecting with each other. Therefore, a complicated spatial effect can be perceived, and the above-described effect can be further improved.
  • FIG. 5 is a diagram illustrating another example of a method for processing a surface of the metal plate 110 according to the present embodiment. In FIG. 5(a), the surface 110a of the metal plate 110 is polished by moving (from right to left in FIG. 5(a)) a plurality of rotary polishing tools 120 (four rotary polishing tools are shown as an example in the present embodiment) while rotating. Accordingly, a plurality of first polishing columns 112a (four columns) are formed whose circular arcs curve to the right. In FIG. 5(b), the surface 110a of the metal plate 110 is then polished by moving (from left to right in FIG. 5(b)) the plurality of rotary polishing tools 120 while rotating between these first polishing columns 112a. Accordingly, a plurality of first polishing columns 112b are formed whose circular arcs curve to the left, that is, a plurality of first polishing columns 112b are formed whose circular arcs are curved in directions opposite to the directions in the first polishing columns 112a.
  • Similarly, in FIG. 5(c), the surface 110a of the metal plate 110 is polished by moving (from bottom to top in FIG. 5(c)) the plurality of rotary polishing tools 120 (three rotary polishing tools are shown as an example in the present embodiment) while rotating. Accordingly, a plurality of second polishing columns 114a (three columns) are formed whose circular arcs curve downward. In FIG. 5(d), then, the surface 110a of the metal plate 110 is polished by moving (from top to bottom in FIG. 5(d)) the plurality of rotary polishing tools 120 while rotating between these second polishing columns 114a. Accordingly, a plurality of second polishing columns 114b whose circular arcs curve upward, that is, a plurality of second polishing columns 114b are formed whose circular arcs are curved in a direction opposite to the directions of the second polishing columns 114a. The surface 110a of the metal plate 110 can thus be efficiently processed by forming a plurality of polishing columns at once using a plurality of rotary polishing tools 120.
  • Note that a stainless steel sheet can be suitably used as the above-described metal plate 110, for example. Accordingly, in addition to high aesthetics and better design, high strength and rust resistance can be attained. However, this is merely an example, and it is appreciated that other metals can be selected in accordance with the required strength or the like. Although a configuration in which the metal plate 110 is disposed on the front surface (front plate 102) of the storage case 100 has been described as an example in the present embodiment, the present invention is not limited to this, and the metal plate 110 can be disposed on any other panel, for example, on a panel constituting the side surface.
  • Also, the above-described embodiment has been described using orthogonal directions extending along the longitudinal (vertical) and latitudinal (horizontal) directions of a square metal plate 110 as exemplary directions in which the first polishing columns 112 (first polishing columns 112a, 112b) and the second polishing columns 114 ( second polishing columns 114a, 114b) intersect with each other. However, the present invention is not limited to this. For example, the first polishing columns 112 and the second polishing columns 114 may be inclined at 45 degrees with respect to the longitudinal and latitudinal directions of the metal plate 110 (90 degrees relative to each other). Also, the first polishing columns 112 and the second polishing columns 114 may intersect with each other at a lopsided (non-orthogonal) angle, instead of orthogonally intersecting with each other.
  • FIGS. 6, 7, 8, 9, and 10 are diagrams illustrating other examples of metal plates. In order to facilitate the understanding, in FIGS. 6 to 10, the rotary polishing tool 120 is depicted as a circle, and polishing columns in which multiple circular arc-shaped polishing marks of the rotary polishing tool 120 are successively formed are depicted with solid lines. Note that a method for processing the surface of the metal plate will also be described while the metal plate will be described. Also, in the description below, constituent elements redundant with the elements that have been described above will be assigned the same reference numerals and their further description will be omitted.
  • A plurality of first longitudinal polishing columns 214a and a plurality of second longitudinal polishing columns 214b are formed on a surface 212 of a metal plate 210a shown in FIG. 6(a), with multiple circular arc-shaped polishing marks being successively formed in a line (linearly) in each polishing column. Also, on a surface 212 of the metal plate 210a, a plurality of first latitudinal polishing columns 216a and a plurality of second latitudinal polishing columns 216b, with multiple circular arc-shaped polishing marks that each curve in the form of a wave being formed in a direction crossing the linear first longitudinal polishing columns 214a and the linear second longitudinal polishing columns 214b, that is, in a direction that is different from the directions of the linear first longitudinal polishing columns 214a and the linear second longitudinal polishing columns 214b. That is, in the metal plate 210a, linear polishing columns and curved polishing columns intersect with each other.
  • When the surface 212 of the metal plate 210a shown in FIG. 6(a) is processed, first, as shown in FIG. 6(b), a plurality of first longitudinal polishing columns 214a that head from top to bottom (in FIG. 6(b)) and a plurality of second longitudinal polishing columns 214b that head in a direction opposite thereto are formed. That is, in FIG. 6(b), the circular arcs of adjacent first longitudinal polishing columns 214a and second longitudinal polishing columns 214b are curved in opposite directions. Accordingly, a polishing pattern in which a plurality of linear polishing columns are arranged in parallel to each other is formed on the surface 212 of the metal plate 210a.
  • Next, as shown in FIG. 6(c), on the surface 212 of the metal plate 210a on which the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b are formed, first latitudinal polishing columns 216a that curve in the form of a wave are formed from right to left (in FIG. 6(c)), that is, first latitudinal polishing columns 216a are formed heading in a direction that is different from the directions of the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b that have been formed earlier (that is, a direction crossing the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b in the present embodiment).
  • As shown in FIG. 6(d), second latitudinal polishing columns 216b that curve in the form of a wave and head in a direction opposite to the direction of the first latitudinal polishing column 216a are formed. Accordingly, as shown in FIG. 6(a), a polishing pattern in which a plurality of first latitudinal polishing columns 216a that each curve in the form of a wave and a plurality of second latitudinal polishing columns 216b that each curve in the form of a wave are arranged in parallel to each other are formed on the surface 212 of the metal plate 210a, superimposed on a polishing pattern in which a plurality of first linear longitudinal polishing columns 214a and a plurality of second linear longitudinal polishing columns 214b are arranged in parallel to each other. That is, in the metal plate 210a, shapes of polishing columns are different for each polishing pattern. Accordingly, the polishing pattern can be more complicated, and the aesthetics of the metal plate 210a can be further improved. Note that although a case where the first longitudinal polishing columns 214a, the second longitudinal polishing columns 214b, the first latitudinal polishing columns 216a, and the second latitudinal polishing columns 216b are formed in the stated order has been described as an example in the above description, the present invention is not limited to this, and the order of formation of these polishing columns can be changed as desired.
  • On a surface 212 of a metal plate 210b shown in FIG. 7(a), a plurality of first latitudinal polishing columns 218a and a plurality of second latitudinal polishing columns 218b are formed, with multiple circular arc-shaped polishing marks being successively formed linearly while bending, that is, multiple circular arc-shaped polishing marks being successively formed in a zigzag form in a direction crossing the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b (in a direction different from the directions of the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b), and superimposed on the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b. That is, on the metal plate 210b, the first linear longitudinal polishing columns 214a and the second linear longitudinal polishing columns 214b intersect with the first zigzagging latitudinal polishing columns 218a and the second zigzagging latitudinal polishing columns 218b.
  • Similarly to the metal plate 210b in FIG. 6(b), when the surface 212 of the metal plate 210b shown in FIG. 7(a) is processed, first, as shown in FIG. 7(b), the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b are formed. Next, as shown in FIG. 7(c), the first zigzagging latitudinal polishing columns 218a that head from right to left (in FIG. 7(c)) are formed on the surface 212 of the metal plate 210b on which the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b have been formed.
  • As shown in FIG. 7(d), then, second zigzagging latitudinal polishing columns 218b are formed that head in a direction opposite to the direction of the first latitudinal polishing columns 218a. Accordingly, as shown in FIG. 7(a), on the surface 212 of the metal plate 210b, a polishing pattern in which the plurality of first zigzagging latitudinal polishing columns 218a and the plurality of second zigzagging latitudinal polishing columns 218b are arranged in parallel to each other is formed, superimposed on the polishing pattern in which the plurality of linear columns 214a and the plurality of linear columns 214b are arranged in parallel to each other. With this configuration as well, a similar effect to that of the above-described metal plate 210a can be obtained. Note that the order of formation of the first longitudinal polishing columns 214a, the second longitudinal polishing columns 214b, the first latitudinal polishing columns 218a, and the second latitudinal polishing columns 218b is not limited to this, and the order of the formation can be modified as desired.
  • On a surface of a metal plate 210c shown in FIG. 8, a plurality of first zigzagging latitudinal polishing columns 218a and a plurality of second zigzagging latitudinal polishing columns 218b are formed in directions crossing the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b (in a direction different from the directions of the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b), and superimposed on the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b. Whereas the first latitudinal polishing columns 218a and the second latitudinal polishing columns 218b are not in contact with each other on the metal plate 210b shown in FIG. 7(a), on the metal plate 210c shown in FIG. 8, the first latitudinal polishing columns 218a and the second latitudinal polishing columns 218b are in contact with each other on the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b. With this configuration as well, a similar effect to that of the above-described metal plates 210a, 210b can be obtained.
  • Note that on the metal plate 210c as well, the order of formation of the first longitudinal polishing columns 214a, the second longitudinal polishing columns 214b, the first latitudinal polishing columns 218a, and the second latitudinal polishing columns 218b is not limited to this, and the order of the formation can be modified as desired. Also, although the first latitudinal polishing columns 218a and the second latitudinal polishing columns 218b are in contact with each other on the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b in the present embodiment, the present invention is not limited to this, and the first latitudinal polishing columns 218a and the second latitudinal polishing columns 218b may be in contact with each other at locations between the first longitudinal polishing columns 214a and the second longitudinal polishing columns 214b.
  • On a surface 212 of a metal plate 210d shown in FIG. 9(a), first linear polishing columns 220a, second linear polishing columns 220b, third linear polishing columns 220c, and fourth linear polishing columns 220d are formed, each polishing column advancing from a corner of the metal plate 210d to its opposite corner. When the surface 212 of the metal plate 210d shown in FIG. 9(a) is processed, as shown in FIG. 9(b), first, the first linear polishing columns 220a that head from the lower left to the upper right of the metal plate 210d are formed.
  • Next, as shown in FIG. 9(c), the second linear polishing columns 220b that head from the upper right to the lower left of the metal plate 210d are formed. Accordingly, as shown in FIG. 9(c), a polishing pattern is formed in which the plurality of first polishing columns 220a and the plurality of second polishing columns 220b that extend between the corner in upper right and the corner in lower left of the metal plate 210d are arranged in parallel to each other.
  • Then, as shown in FIG. 9(d), third linear polishing columns 220c that head from upper left to lower right of the metal plate 210d are formed, and as shown in FIG. 9(e), fourth linear polishing columns 220d that head from the lower right to the upper left of the metal plate 210d are formed. Accordingly, as shown in FIG. 9(a), on the surface 212 of the metal plate 210d, a polishing pattern in which a plurality of the third linear polishing columns 220c and a plurality of the fourth linear polishing columns 220d are arranged in parallel to each other is formed, superimposed on a polishing pattern in which the plurality of first linear polishing columns 220a and the plurality of second linear polishing columns 220b are arranged in parallel to each other. With this configuration as well, a similar effect to those of the above-described metal plates 210a to 210c can be obtained. Note that in the step of polishing the metal plate 210d shown in FIG. 9(a) as well, the order of formation of the first polishing columns 220a to the fourth polishing columns 220d can be defined as desired.
  • On a surface 212 of a metal plate 210e shown in FIG. 10(a), first longitudinal polishing columns 222a and second longitudinal polishing columns 222b that each curve in the form of a wave are formed in directions crossing the first latitudinal polishing columns 216a and the second latitudinal polishing columns 216b that each curve in the form of a wave (in a direction different from the directions of the first latitudinal polishing columns 216a and the second latitudinal polishing columns 216b), and superimposed on the first latitudinal polishing columns 216a and the second latitudinal polishing columns 216b. When the surface 212 of the metal plate 210e shown in FIG. 10(a) is processed, as shown in FIG. 10(b), first, the first latitudinal polishing columns 216a that head from right to left (in FIG. 10(b)) are formed. Then, as shown in FIG. 10(c), the second latitudinal polishing columns 216b that head in a direction opposite to the directions of the first first latitudinal polishing columns 216a are formed. Accordingly, a polishing pattern in which a plurality of first latitudinal polishing columns 216a and a plurality of second latitudinal polishing columns 216b are arranged in parallel to each other, each column curving in the form of a wave, is formed.
  • Then, as shown in FIG. 10(d), first longitudinal polishing columns 222a are formed that each curve in the form of a wave and head from top to bottom (in FIG. 10(d)), and as shown in FIG. 10(e), second longitudinal polishing columns 222b are formed that each curve in the form of a wave and head in a direction opposite to the direction of the first longitudinal polishing columns 222a. Accordingly, as shown in FIG. 10(a), on the surface 212 of the metal plate 210e, a polishing pattern is formed in which a plurality of the first longitudinal polishing columns 222a and a plurality of the second longitudinal polishing columns 222b are arranged in parallel to each other, superimposed on a polishing pattern in which the plurality of first latitudinal polishing columns 216a and the plurality of second latitudinal polishing columns 216b are arranged in parallel to each other, each column curving in the form of a wave. With this configuration as well, a similar effect to that of the above-described metal plates 210a to 210d can be obtained. Note that the order of formation of the polishing column on the metal plate 210e can also be modified as appropriate.
