PROBLEM TO BE SOLVED: To provide a technology by which a bonded magnet that is excellent in flexibility and has a high coercive force can be obtained. SOLUTION: After a magnetic sheet containing magnetic powder and a binder which bonds the magnetic powder is obtained, the magnetic sheet is rolled while the sheet is maintained in a prescribed heated state. Since the magnetic sheet is rolled while the sheet is maintained at a temperature higher than the normal temperature, the stress imparted to the magnetic powder at rolling time can be reduced. Consequently, the bonded magnet having the high coercive force can be obtained. It is desirable to adjust the temperature of the magnetic sheet to 25-80°C when the sheet is rolled. The product is appropriately used especially for a bonded magnet containing a crosslinking agent. COPYRIGHT: (C)2005,JPO&NCIPI
