限されていた。As described above, a magnet sheet having the convenience of being detachably magnetically attached to a magnetic material surface has a large magnetic material surface in offices and the like where many steel fixtures are used. Although it is widely used for this purpose, permanent magnets such as magnet sheets are used in places such as homes where there are few steel furniture and furniture other than refrigerators etc. because there are few magnetic surfaces on which magnet sheets can be magnetically attracted. The use of various magnet-applied products having a substrate as a base has been restricted.

ある。FIG. 1 shows a first embodiment of a soft magnetic sheet according to the present invention. In the figure, 1 is a soft magnetic sheet, and 2 is a ferromagnetic material having a large magnetic permeability and a high coercive force. A magnetic sheet formed to a thickness of 0.1 to 1.0 mm by mixing and kneading a soft magnetic powder such as small soft ferrite powder or iron powder and a synthetic resin material, and 3 is adhered to one surface of the magnetic sheet 2 The sticking means 4 formed of a removable adhesive formed is a sheet body made of a synthetic resin sheet or film, paper, or the like, which is adhered to the surface of the magnetic sheet 2 opposite to the sticking means 3, that is, the surface. . 5 is a wall surface to which the soft magnetic sheet 1 is adhered.

たいと称し、永久磁石などに用いられる。The magnetic sheet 2 alone has the same flexibility as that of a conventional magnet sheet, but has a soft magnetic property such as soft ferrite powder or iron powder used for the magnetic sheet 2 of the present invention. The material does not become a permanent magnet, and among the ferromagnetic materials, those with high magnetic permeability and low coercive force make it easy for magnetic flux to enter, and when the direction of an external magnetic field is changed, the magnetization tends to change accordingly. It is said that such a property is magnetically soft and the magnetism is soft. On the other hand, a ferromagnetic material having a large coercive force is referred to as magnetically hard, not according to the change of the external magnetic field, and is used for a permanent magnet or the like.

る。The sticking means 3 is for sticking the magnetic sheet 2 to a wall, window, pillar, partition, door or the like made of a non-magnetic material such as glass, aluminum, wood, plastic, concrete, plaster board and the like. Yes,
A so-called re-peelable adhesive that can be repeatedly bonded is applied to the whole or part of the back surface of the magnetic sheet 2. Further, in the present invention, not only the structure in which the sticking means 3 is previously formed on the back surface of the magnetic sheet 2 but also the liquid May be applied.
When a re-peelable adhesive is used as the sticking means 3, unlike a hard-to-peel adhesive, even if the soft magnetic sheet 1 is peeled, there is no possibility that the wall surface will be damaged or stained, and the adhesive remains. In addition, the soft magnetic sheet 1 can be reused.

It is preferable that the surface 4 is formed on the surface of the magnetic sheet 2 so as to bring out the beauty. Further, it is also possible to use a method in which a wall decoration such as wallpaper having a thin magnet sheet adhered to the back surface is entirely magnetized on the surface of the soft magnetic sheet 1. In this case, anyone can easily and easily replace the wall decorative body in a very short time without using an adhesive or a tool that has been conventionally required. In addition, the wall decorative body having such a thin magnet sheet adhered to the back surface is made thin enough to be loaded into a printer, so that a desired pattern or the like can be freely drawn by a computer output.

シートを用いることができる。As described in detail above, the soft magnetic sheet of the present invention is mixed with a soft magnetic powder of soft ferrite powder or iron powder and a synthetic resin material and kneaded to form a sheet having a thickness of 0.1 to 1.0 mm. An adhesive that can be repeatedly bonded to one side of the magnetic sheet
On the other side, a sheet or film made of synthetic resin,
By attaching a sheet of paper or the like , this soft magnetic sheet can be permanently attached to walls, windows, columns, partitions, doors, etc. where there is no magnetic material surface, and permanent The magnets can be detachably magnetized, and the use places are wide-ranging for various types of magnet products which have conventionally been limited to use on magnetic surfaces such as steel boards and white boards. Further, since the soft magnetic sheet of the present invention is thin and flexible, it can be stuck not only on a flat surface but also on a slightly curved surface .
Also, adhesive that can be repeatedly bonded to one side of the magnetic sheet
The By the deposited and formed, when adhering the magnetic sheet on the wall surface or the like, labor is not required for depositing an adhesive or the like to the magnetic sheet, along with acceleration of the works is achieved, unlike the peeling difficult adhesive , Even if the soft magnetic sheet is peeled, the wall surface is damaged,
There is no risk of fouling and no adhesive remains, and the soft magnetic sheet can be reused . Also, on the surface opposite to surface sticking means or magnet sheet is attached in the magnetic sheet, a sheet or film of synthetic resin, a sheet such as paper by depositing various color on the sheet body, picture, pattern The soft magnetic sheet of the present invention can be used as a wallpaper having a beautiful feeling by printing.
