| 摘要 |
A laminated device comprising pluralities of magnetic ferrite layers, conductor patterns each formed on each magnetic ferrite layer and connected in a lamination direction to form a coil, and a non-magnetic ceramic layer formed on at least one magnetic ferrite layer such that it overlaps the conductor patterns in a lamination direction, the non-magnetic ceramic layer comprising as main components non-magnetic ceramics having higher sintering temperatures than that of the magnetic ferrite, and further one or more of Cu, Zn and Bi in the form of an oxide.
