    摘要: A magnetic sheet, which contains: a magnetic layer including a magnetic powder and a resin composition containing the magnetic powder therein; and a convex-concave forming layer, in which the convex-concave forming layer has Bekk smoothness of 70 sec/mL or less. A method for producing a magnetic sheet, which contains: adding a magnetic powder to a resin composition to prepare a magnetic composition, and giving the magnetic composition a shape to form a magnetic layer; and placing and stacking a convex-concave forming layer and a pattern transferring material on a surface of the magnetic layer in this order, and hot pressing the stacked layers so as to bond the convex-concave forming layer with the magnetic layer to form a laminate, as well as to transfer a surface configuration of the pattern transferring material to a surface of the laminate of the convex-concave forming layer and the magnetic layer.

    摘要: The present invention provides an antenna apparatus (60) for use in a non-contact type IC card into and from which data can be written and read by an electronic apparatus having a communication function, by virtue of inductive coupling. The antenna apparatus includes a loop coil (61) and a magnetic member (62). The loop coil (61) is produced by winding a conductive wire in a plane and configured to perform the inductive coupling with the electronic apparatus. The magnetic member (62) covers one region (61a) of the loop coil, provided at one side, from one surface of the loop coil, passes through the loop coil, and covers the other region (61b) of the loop coil, provided at the other side, from the other surface of the loop coil.

    摘要: The present invention is to impart, to a sheet-like soft magnetic material, a configuration in which sheet thickness change is suppressed and in which fluctuation in magnetic permeability is small even under a high-temperature or a high-temperature, high-humidity environment, even when a plurality of thin curable soft magnetic sheets produced by a coating method are laminated. The sheet-like soft magnetic material is formed from a soft magnetic composition which is formed by mixing at least a flat soft magnetic powder, an acrylic rubber, an epoxy resin, a curing agent for the epoxy resin, and a solvent. The flat soft magnetic powder is arranged in an in-plane direction of the sheet-like soft magnetic material. An acrylic rubber having a glycidyl group is used for the acrylic rubber. The weight ratio of the flat soft magnetic powder with respect to the total amount of the acrylic rubber, the epoxy resin, and the curing agent for the epoxy resin is 3.7 to 5.8.
