1. An LC composite component, characterized by:

  • the disclosed device is provided with;

    1 or more inductors;

    1 or more capacitors;

    a magnetic layer having magnetism; and

    a substrate supporting the 1 or more inductors, the 1 or more capacitors, and the magnetic layer,the substrate has a 1 st surface and a 2 nd surface opposite to the 1 st surface,the magnetic layer is disposed so as to oppose the 1 st surface of the substrate,the 1 or more inductors are disposed between the 1 st surface of the substrate and the magnetic layer,between the 1 or more inductors and the 1 st surface of the substrate, there is no magnetic layer,a thickness of the substrate is larger than a thickness of the magnetic layer in a direction perpendicular to a 1 st face of the substrate,the real part and the imaginary part of the complex magnetic permeability of the substrate are respectively smaller than the real part and the imaginary part of the complex magnetic permeability of the magnetic layer,the LC composite component does not include inductors other than the 1 or more inductors,the LC composite component does not include capacitors other than the 1 or more capacitors,each of the 1 or more capacitors does not overlap any of the 1 or more inductors when viewed from a direction perpendicular to the 1 st surface of the substrate.
