PROBLEM TO BE SOLVED: To suppress ignition to the powder caused by the oxidation of the powder by improving the heat resistance of the sheet in a flexible magnet sheet containing a rare-earth-based ferromagnetic material as a magnetic component and at the same time, to improve the appearance of the magnetic attracting surface of the sheet. SOLUTION: On the surface of the flexible magnet sheet containing the powder of the rare-earth-based ferromagnetic material as the magnetic component or on the surface of the magnetic layer of the sheet, a self-extinguishing film is formed by coating. At forming the self-extinguishing coating layer, such a substance as the aluminum hydroxide, etc., which presents white color at the time of forming the coating layer is used as a self-extinguishing property imparting agent. |
