Method For Producing Magnetic Sheet

Abstract: Provided is a highly productive method which is for producing a magnetic sheet and which reduces the number of times of winding and unwinding, wherein the magnetic sheet is provided with excellent magnetic properties and good isotropy. The method for producing a magnetic sheet comprises: a heat treatment step for making an amorphous alloy ribbon into a nanocrystalline alloy ribbon by heating; and an attachment step for attaching an adhesive layer to one surface of the nanocrystalline alloy ribbon. In the heat treatment step, a ribbon pressing member is brought into contact with a surface of the amorphous alloy ribbon opposite to a surface of the amorphous alloy ribbon in contact with a heating body, and a tension of 18a or less is applied to the amorphous alloy ribbon. The attachment step is performed continuously with the heat treatment step, and in the attachment step, the adhesive layer is attached to said one surface of the nanocrystalline alloy ribbon while the nanocrystalline alloy ribbon is being transferred.
