Manufacturing method of the inductance components, magnetic bias applying member and a magnetic bias applying member

摘要

A magnetic core body 12 having a gap 16 for preventing magnetic saturation at at least one position of a magnetic path and a magnetic core 10 disposed in the air gap 16 and having a magnetic bias applying member 14 made of a material different from that of the magnetic core body 12 And a conductive wire 20 attached to the magnetic core 10. The magnetic bias applying member 14 is made of a hard magnetic material powder for applying a magnetic bias, a soft magnetic material powder for improving the relative magnetic permeability, and a binder for bonding them Wherein the composite magnetic material is formed by shaping the composite magnetic material contained therein into a flat plate shape. According to the magnetic device of the present invention, a magnetic device having excellent direct current superimposition characteristics and small variations in magnetic characteristics is obtained.
