    Abstract: An LC composite component includes a non-magnetic substrate, a magnetic layer with magnetism, capacitors, inductors, and core parts with magnetism. The non-magnetic substrate includes a first surface and a second surface on a side opposite to the first surface. The magnetic layer is disposed to face the first surface of the non-magnetic substrate. The inductors and the capacitors are disposed between the first surface of the non-magnetic substrate and the magnetic layer. The core parts are disposed between the first surface of the non-magnetic substrate and the magnetic layer and connected to the magnetic layer. The thickness of the core parts is 1.0 or more times the thickness of the magnetic layer in a direction perpendicular to the first surface of the non-magnetic substrate, and each of the magnetic layer and the core parts contains magnetic metal particles and resin.
