PURPOSE:To make a process simple and to enable mass production by pressing a pattern, a letter, a symbol, etc. simultaneously with the formation of a permanent magnet itself. CONSTITUTION:A magnet 1 is made of a synthetic resin mixed with magnetic powder and a pattern 2, a symbol, a letter, etc. are pressed on the surface 1a of the magnet 1 at the time when the magnet is formed by molding, hot press, etc. and the pattern 2, etc. have a curved surface region 2a on all or part of a recessed surface. The surface 1a of the permanent magnet 1 is plated, the recessed surfaces of the pattern 2, the symbol, the letter, etc. are also covered with a plate film 3 and the plate film 3 is formed to a recessed curve surface and to have partially a concave surface. |
