Description of the Invention: [Technical Field of the Invention] The present invention relates to two mask sheets in an adhesive layer, and particularly to a workability for mounting in an electronic device. Hot #位等 [previous technique] raw sheet. In recent years, in the fields of precision parts, electrical, and the two sides to which the joined materials are joined together, and the like, and the high-performance properties such as the adhesiveness and electromagnetic wave absorption required for these two sides are required. At the same time, there are many requirements for the V hot spot, considering the workability and the high workability. For example, in Patent Document 2, the end portion of the release paper of the material (adhesive layer) is two sheets: the sheet is sandwiched, and the two sides of the side protrusion are then cut. The end of the sheet of the station is disclosed in the patent document 1 : 曰 专利 专利 1, 1, 1, 【 【 【 【 【 【 【 【 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( Since the end of the adhesive sheet on both sides of the sheet is peeled off from the two ends of the paper, it is necessary to prepare another sheet of the release paper to be laminated on both sides of the second layer of the paper. complex. Further, at the end of the two sheets of release paper: on the sheet, when the production step is very high, a piece of the release paper is used, and when it is desired to peel off the chicken, it is operated. 97112563 200920809 Good two-sided adhesive sheet = easy to make, and the solid part of the working device is used for the two-sided adhesive sheet suitable for use in the electronic machine (the means to solve the problem). The present invention is a two-sided Le Bo, which is provided on the surface of the other surface of the surface of the micro-[i] surface, which is attached to the sheet-like adhesive layer, and is characterized in that: the second peeling paper is provided on the other side, and the second peeling is provided. Both end portions of the paper and at least one end portion of the second release paper have the same end portions of the first release paper in the width direction of the adhesive layer; the length of the adhesive layer is longer than The ends of the adhesive layer are aligned to the outer side and the ends of the adhesive layer are aligned. (Effect of the Invention) 2. Since the end portion of the second release paper protrudes outward from the adhesive layer and the second peeling projection, the second peeling paper can be used as a picking strip (pickup (10), which is easy to use with a finger or ^. Holding the pick-up strip, the second release paper together with the adhesive layer is further "attached to the end of the width direction of the second release paper" so that the adhesive layer is attached to the member to be joined and transferred, It is also easy to align the position, and it is easy to carry out the attaching work. The double-sided adhesive sheet of the present invention can be easily formed by forming the first release paper, the adhesive layer and the second release paper by the following means. After the body, the step is to remove the excess by half-cutting. Therefore, the adhesive sheets on both sides of this month are suitable for mass production and can be provided at low cost. In addition, it can be combined with 97112563 200920809, and each layer will be The one-layered body is cut and then subjected to the half-cutting, so that it can be mass-produced with higher efficiency. [Embodiment] Fig. 1 is a perspective view of a preferred embodiment of the double-sided adhesive sheet of the present invention. Section of the embodiment of Figure i The schematic view is shown in Fig. 3. Fig. 2 is a schematic cross-sectional view of the longitudinal direction of the strip-shaped adhesive layer 2 in the width direction of the two-series strip-like adhesive layer 2. ° Coffin: 22:3, basic The double-sided adhesive sheet of the present invention is attached to a γ-sheet adhesive layer (hereinafter, referred to as a first release paper sheet, and a layer body is provided on the other surface). As shown in FIG. 2, in the formed product 'X', as shown in FIG. 2, the end portions of the first release paper 1 in the direction in which the adhesive layer 2 peels the paper 3 and the direction of the adhesive layer 1 are the same. The direction of the direction is inconsistent, but also - έ 'Fig. 2 and the end of the adhesive layer 2, at least - the end of the adhesive layer 1 is preferably as shown in Figure 2 'the first peeling paper 1 When the first release paper is joined to the side of the second release paper, the reason is that the layer 2 is separated from the first release paper portion by the layer 2 such as a finger, and the paper is easily peeled off. In the invention, as shown in Fig. 3, at least the mountain of the second release paper 3 is in the longitudinal direction of the adhesive layer 2. When the paper sheet 3 is farther than the end portion of the layer 2, the end portion is peeled off to the outside. At the time of the second release paper dot layer 2, the portion from the first release paper i becomes a pickup %. = The end of the layer 2 protrudes outward from the 97112563 Yin, and is 1st in the length direction of the adhesive layer 2 200920809. The end portions of the peeling crucible 1 and the end portions of the adhesive second release paper 3 are aligned with respect to the two of the two, that is, both the end portion of the 1 J layer 2 and the first release paper protrude outward, when using a finger or When the small tweezers are held or the like, the end portion of the first release paper i is not in contact with each other: it is an obstacle, and the door can be easily gripped. The peeling operation of the second release paper 3 together with the adhesive layer 2 is relatively easy to delete. In the invention, it is considered that the self-adhesive layer 2 of the release paper 3 is processed into a specific shape 苐2 and the paste is taken! It is better that the length of the part of ^^^^ is better than that of the small part of the town, it is not easy to hold the protruding part H13, the Japanese temple, the finger or 25 mm, which may cause the product yield to drop. difference. Further, when the end of the second release paper 3 is longer than the end of the adhesive layer 2, the end portion of the second release paper 3 may be located at a large end portion of the longitudinal direction of the adhesive layer 2, and at the both end portions. The length of the highlight is two or two = different. In the case where the two ends are protruded, the two ends can be taken. Pulling up the stringer is preferable when attaching the adhesive layer 2 to the member to be joined. In particular, when the length of the adhesive layer 2 is long, it is possible to prevent the occurrence of distortion or the like by picking both end portions, so that the operation can be further used in the present invention. The following form can be preferably used: ! Stripping paper! The laminate of the plurality of adhesive layers 2 and the second release paper 3 is disposed along the θ of the adhesive layer 2. In the wide direction, a plurality of laminated bodies can be brought into contact with each other and closely arranged, and the adhesive layer 2 is adhered to each other between the structural layer bodies, so that when each of the adjacent layers is separated, it is difficult to peel off or cause Adjacent laminated body is also allowed to be 7112563 200920809 = the second is preferably as shown in FIG. 2 and FIG. 2, in the width direction of the adhesive layer 2, Wei t. The strips are arranged with a gap between them. The 9th ί of the gap is 〇.5 _ or more and less than the width of the article (i.e., the thickness of the adhesive layer 2 and the layer except the layer). If the gap is smaller than the G.5 leg, the labor cost to 盥° will increase, and if the gap increases the gap, the product ί = will not only have a large loss, but also cause the I σ σ to be easily removed. Stripped together, so it's not good. 'As shown in the viscosity SI 2, a plurality of layers of the first release paper 1 are disposed on the first layer: the laminate of the release paper 3, by means of a finger or the like; J is separated from the laminated body of the paper 1 The configuration area makes it easier to peel off the new accumulation sound # 斑第9, 曰 Body and 'with each adhesive layer 2 =, ^ 3's laminate using a piece of 帛1 peeling paper 1 structure phase ^ ^The number of pieces of the first release paper 1 of the waste is reduced, so the waste < volume is reduced, and it is preferable. In the invention, the second release paper 3 and the adhesive layer 2 are missing from the first y ^From then, the adhesive layer 2 is attached to the first joined structure 3: the i 2 release paper 3 is peeled off from the adhesive layer 2, and the second joined member is attached to the exit surface of the adhesive layer, thereby The member is joined to the second member to be joined. Therefore, the force of m is greater than the adhesion of the first release paper 1 to the adhesive layer 2, and the body is preferably (the second release paper 3 and the adhesive layer 2) The adhesive force of the release paper 1 and the adhesive layer 2 is ～3~5/2. If the adhesive force ratio is less than 3/2, the second peeling 3 and the adhesive layer 2 are peeled off from the first layer. Paper! When peeling off, there will be 97112563 2 00920809 = 2 peeling: If the paper 3 and the adhesive layer 2 are peeled off, if it is larger than ι〇", the first peeling paper i is outside the specific work, and since #(四) is separated, the workability is lowered, so Poor. As 哕θ: adjustment method, the ith release paper and the second release paper can be changed: the adhesive force on the side in contact with the first release paper 1 is higher than the contact with the second release paper 3. The member of the double-sided adhesive sheet of the present invention will be described. In the present invention, the term "the ii-th release paper" and the second release paper 3 refer to a member such as a release liner, a separator, and a release paper. For the release paper used in three types, paper, resin or metal box release paper whose surface is subjected to polyfluorination stripping treatment or fluorine separation treatment may be selected, and paper is specifically considered to use cellophane and paper. It is obtained by using a forest paper, a kraft paper, or a filling treatment with polyethylene, and various synthetic resins can be used for the resin. Specifically, polyvinyl chloride or polyethylene terephthalate (polyethylene terephthalate) can be used. PET, polyethylene terephthalate), ethylene-vinyl acetate copolymer Ethylene-ethyl acrylate copolymer, polyethylene, polypropylene, ethylene-acrylic acid copolymer, ionomer resin, polyimine, polyethylene naphthalate, etc. Further, a multilayer film of the above resins may be preferably used. Further, as the metal box-based release paper, there may be mentioned, for example, a foil, a copper foil, a tin foil, etc. The thickness of the release papers 1 and 3 is not In particular, in consideration of the cutting or half-cutting processing in the following manufacturing steps, it is preferably 5 〇 " m or more.

For example, in the case of the embodiment of Fig. 1, first, a laminate including the first peeling layer, the first layer 1, the adhesive layer 2, and the second release paper 3 is formed, and then the second release paper 3 is adhered toward the lower side. In the longitudinal direction of the layer 2, the laminated body is half-cut into a specific length by a punching machine, and the first release paper 1 and the adhesive layer 2 on the short side are peeled off from the second release paper 3 to obtain a second release paper 3 Take the lead. Then, the first release paper 1 is directed downward, and the laminated body is half-cut into a specific width by a punching machine, and the adhesive layer 2 and the second release paper 3 of the gap portion are peeled off from the first release paper 1. Further, in the present invention, as described above, after the layered body including the first release paper 1, the adhesive layer 2, and the second release paper 3 is formed, half-cut QJ processing is performed, thereby forming a plurality of large areas. The laminate is used as the laminate ~ : 'cutting one parent laminate' and then performing half-cut processing, which can be manufactured with higher efficiency at 97112563 12 200920809. [Examples] A double-sided adhesive sheet having the shape shown in Fig. 1 was produced as an example. - 1st release paper: obtained by peeling treatment on one side of a PET film having a thickness of 50 #m. The second release paper: one obtained by peeling treatment on one side of a PET film having a thickness of 75 #m. f „ Furthermore, the first peeling paper and the second release paper are both 170 mm×1.61 mm. Resin composition for adhesive layer: Acrylic rubber of ίο% by mass% (Ze〇n) limited stock In the "2EHA" solution of "AR-53L" manufactured by the company, "2EHA" manufactured by Toagosei Co., Ltd., mixed with 1% by mass of acrylic acid ("AA" manufactured by Toagosei Co., Ltd.) Then, 0.5% by mass of a photopolymerization initiator 2,2-dimethoxy-oxime, 2-diphenylethyl 1 mesh (manufactured by Ciba Specialty Chemicals Co., Ltd.), 0.2 was added. 3% by mass of ethylene glycol dithiol (manufactured by Maruzen Chemical Co., Ltd.) and 2% by mass of 2-butyl- 2-ethyl-1,3-propanediol diacrylate (Kyoeisha Chemical Co., Ltd.) Made by the company) and mixed 'to obtain a resin composition. One part by mass of the resin composition was mixed with 750 parts by mass of alumina, which is a thermal conductive filler ("Electric Chemical Industry Co., Ltd."), for vacuum defoaming ( 0.08 MPAx 60 min) treatment to obtain a thermally conductive resin composition. Applying the above-mentioned heat conduction to the surface of the second release paper subjected to the release treatment, and forming the article 'to a thickness of 1 〇〇# m ' on the coated surface of the coated surface 97112563 13 200920809 ' 'In order to prevent the air from entering the 'UV from the back side of the watch with 3 〇〇" j/cffl 365 nm, an adhesive layer is formed. The film covering the coated surface is peeled off, and the "peel release paper" is removed. The side faces the adhesive layer and is laminated, and a laminate including the first release paper, the adhesive layer, and the second release paper is obtained. The above-mentioned laminated body is placed in a punching machine, and the second release paper is directed to the lower side, and the length of the second release paper is half-cut by a puncher to a length of 150-4, and the two sides are peeled off and removed! Strip the paper and the adhesive layer. Say on both sides of the > into a length of 1 〇 mm picking lead. Then, the first release paper is directed to the lower side, the feed hole of the puncher is adjusted to be I and = 'the width of the adhesive layer is 3.4, the gap is °. 5 _, and the first release paper is oriented in the width direction. The upper part of the self-adhesive layer is outwardly: "exfoliation removes the gap and the adhesive layer at both ends and the second peeling, I." The shovel is provided with four layers of the width of the 3-4 coffee and the layer of the second _ paper, and the four laminated systems are arranged in parallel with each other. Adhesive sheets on both sides. The two-sided adhesive sheet (adhesive force of the second release paper and the adhesive layer) / (adhesion of the first release paper to the adhesive layer) was 2/1. f. The two-sided "sheet" of the present embodiment is peeled off from the ith release paper by the pick-up strip of the second release paper which can be easily protruded, and is attached to the high-precision state in the state of holding the pick-up strip.牿定φ工%, Part of the 丨 丨 乃 乃 , 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 After the member is pasted, the second release paper is peeled off, whereby the adhesive layer is transferred to the member to be joined, 97112563 200920809, and then the other joined member is adhered to the adhesive layer, whereby the bonding can be satisfactorily achieved. In the step of causing the second release paper to face downward and half-cutting in the above embodiment, the second release paper is also removed, and both surfaces of the pickupless strip are obtained: an adhesive sheet.
