<P>PROBLEM TO BE SOLVED: To provide a multilayer structure of a bonded magnet having two or more kinds of various magnetic properties by forming magnetic powder material having an optimum magnetism suitable for a service part with resin, various rubber or the like and sheeting it. <P>SOLUTION: The bonded magnets are double formed with magnetic powder having high magnetic properties provided inside diameter part and outside diameter part of a low cost bonded magnet which is molded by resin and has low magnetic properties. Various rubber magnetic sheets are made by laminating or integrating the low cost bonded magnetic sheet which has the low magnetic properties on one side with the bonded magnetic sheet using magnetic powder material having the high magnetic properties on the other side. <P>COPYRIGHT: (C)2004,JPO |
