发明名称 Magnetic sheet and production method thereof
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.
