When the sheet-like magnetic body 1A is produced, the step of drying the magnetic layer 3 in the manufacturing step of the sheet-like magnetic body 1 is performed by a letterpress printing machine (not shown) after the step of forming the hard coating layer. The body will turn the ink

2186-9352-PF 17 200913870 Printed on the other side surface of the resin body 2 to form a printing portion (printing portion forming step). Further, the other steps are the same as those of the sheet-like magnetic body 1. In the sheet-like magnetic body u, since the hard coating layer 4 is formed on the other side surface of the resin body 2, the surface of the resin body 2 can be protected from friction by the hard coating layer 4.

Further, the other side surface side of the sheet resin body 2 (the lower side surface side in the same figure is t = the laminated adhesive layer 5 and the peeling (four) 6), which is also different from the sheet ΙΑ, 1B. When the above-described sheet-like magnetic body 1D is produced, the step of drying the magnetic layer 3 in the manufacturing step of the sheet-like magnetic sheet 1 is performed, and after the hard coating layer is formed into a V-step, a letterpress printing machine which is not shown is used. The plate body transfers the ink onto the surface of the magnetic film to form the printing portion 7 (printing portion forming step). Further, in the hard coating layer forming step, the hard coating layer 4 is covered to cover the printing portion 7. The method is formed on the surface of the magnetic layer 3, and in the adhesive layer forming step, the adhesive layer 5 and the release paper 6 are sequentially attached to the other surface side of the resin body 2. Further, other steps are The plate-like magnetic body 1 is the same. In the plate-like magnetic body 1D, since the hard coating layer 4 is formed on the other surface of the resin body 2, the sheet-like magnetic body MA to 1C can be used. In general, it can greatly reduce the scratch on the surface of the sheet-like magnetic body itself. In the 1D, since the printing unit 7 is not directly exposed on the surface of the sheet-like magnetic body 1D, scratching and peeling of the printing unit 7 can be reliably prevented. Next, referring to Fig. 6, the sheet-like magnetic body 1E is used. Constructing

2186-9352-PF 21 200913870 Description. The same component parts as those of the sheet-like magnetic material 1C are denoted by the same reference numerals, and the description thereof will be omitted. As shown in Fig. 6, the sheet-like magnetic body 1E is composed of a sheet-like resin body, two magnetic layers 3, 3, a hard coat layer 4, an adhesive layer, and a rip-off paper 6. The sheet-like magnetic body 1E is formed on one side surface of the resin body 2 (here, the upper side surface in the same drawing) and the other side surface (here, the lower side surface in the same drawing). The upper side (both sides of the resin body 2) forms the magnetic layer 3, which is different from the sheet-like magnetic body 1C. When the above-described sheet-like magnetic body 1E is manufactured, in the manufacturing step of the sheet-like magnetic body 1, after the magnetic layer 3 is formed on one side surface of the resin body 2, it is again on the other side surface of the resin body 2. A magnetic layer 3 is also formed. Here, a primary forming method in which the two magnetic layers 3 are simultaneously formed on both faces of the resin body 2 can also be employed. Further, in the hard coating layer forming step, a hard coating layer 4 is formed on one of the two magnetic layers 3, 3, and an adhesive layer 5 is sequentially disposed on the other surface of the two magnetic layers. Release paper 6. In addition, the other steps are the same as the sheet-like magnetic body. In the sheet-like magnetic body 1E, since the hard coating layer 4' is formed on the surface of the magnetic layer 3, the surface of the magnetic layer 3 can be protected from damage such as friction by the hard coating layer 4, Further, in combination with the hard coating layer 4 itself, it is difficult to combine the scratches, and the scratches on the surface of the sheet-like magnetic body itself can be greatly reduced. Further, since the magnetic layer 3 is formed on both surfaces of the resin body 2 by the sheet-like magnetic body 1E, the shielding property against electromagnetic waves can be sufficiently improved. The person-person is referred to the structure of the sheet-like magnetic body 丨F with reference to FIG.
