Patent ID: 7375608

Claim:
A multi-layer magnetic part, comprising: a composite sheet which is constituted by a central magnetic pattern that is formed by drying a magnetic body paste applied to a substrate and peeling the dried magnetic body paste from the substrate, a dielectric pattern that is formed so as to surround said central magnetic pattern by drying a nonmagnetic body paste applied to said substrate and peeling the dried nonmagnetic body paste from the substrate, and a peripheral magnetic pattern that is formed so as to surround said dielectric pattern by drying a magnetic body paste applied to said substrate and peeling the dried magnetic body paste from the substrate; a primary winding or secondary winding, or both such primary and secondary windings, provided on one face of the dielectric pattern and around the center; a primary winding or secondary winding, or both such primary and secondary windings, provided on the other face of the dielectric pattern and around the center; and a pair of magnetic sheets which are obtained by applying a magnetic body paste to a substrate and drying the paste and which hold the composite sheet and the primary and secondary windings from both sides and contact one another via the magnetic pattern.
