Abstract:
     A composite electric part of a stacked multi-layer structure is composed of a capacor layer and a coil layer. The coil layer comprises a plurality of coils buried in a magnetic material. At least one of the colis includes a plurality of coil conductors which comprises combinations each of two coil conductors wound spirally in opposite directions around respective winding axes extending substantially coaxially with each other, and mutually connected such that magnetic fields are generated in a same direction by the two coil conductors. A miniature size of composite electric part exhibiting a high inductance value is realized.
