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.

Abstract: A coil component includes a coil and a composite magnetic material containing magnetic particles. The magnetic particles have an average minor-axis length of more than 5.0 nm and 50 nm or less and an average aspect ratio of 2.0 or more and 10.0 or less. The magnetic particles are orientated substantially perpendicularly to a central axis of the coil and are orientated randomly within a perpendicular plane to the central axis of the coil. The composite magnetic material has a saturation magnetization σs of 80.0 emu/g or more.
