Claim:
1. An LC composite component comprising: one or more inductors; one or more capacitors; a magnetic layer having magnetism; and a substrate for supporting the one or more inductors, the one or more capacitors and the magnetic layer, wherein the substrate has a first surface, and a second surface opposite to the first surface, the magnetic layer is disposed to face the first surface of the substrate, the one or more inductors are disposed between the first surface of the substrate and the magnetic layer, no magnetic layer is present between the first surface of the substrate and the one or more inductors, the substrate has a thickness greater than that of the magnetic layer in a direction perpendicular to the first surface of the substrate, and the substrate has a complex permeability having a real part and an imaginary part that are respectively smaller than a real part and an imaginary part of a complex permeability of the magnetic layer.
