<P>PROBLEM TO BE SOLVED: To provide a magnetic element in which a vibration generated by an electrification operation is small, cracking due to a thermal stress does not occur easily, and good heat dissipation is ensured. <P>SOLUTION: In a magnetic element 1 where a magnetic member 1a and a coil 2 are molded integrally, the magnetic member 1a is partitioned into two or more by a partition 4 consisting of a nonmagnetic body in the direction not impeding magnetic flux which is parallel with a central axis of the coil 2. The magnetic element has mechanical properties (e.g. a modulus of elasticity, density), and the like, which are different from each other among the partitioned parts. Furthermore, the nonmagnetic body of the magnetic element has a modulus of elasticity different from that of the magnetic member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
