Abstract: An LC composite component includes one or more inductors, one or more capacitors, a magnetic layer, and a substrate. 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. The substrate has a thickness greater than that of the magnetic layer in a direction perpendicular to the first surface of the substrate. The substrate has a complex permeability having a real part and an imaginary part that are respectively smaller than the real part and the imaginary part of the complex permeability of the magnetic layer.

Abstract: Disclosed herein is an electronic component that includes a first conductive layer including a lower electrode and a first inductor pattern, a dielectric film that covers the lower electrode, an upper electrode laminated on the lower electrode through the dielectric film, an insulating layer that covers the first conductive layer, dielectric film, and upper electrode, and a second conductive layer formed on the insulating layer and including a second inductor pattern. The first and second inductor patterns are connected in parallel through via conductors penetrating the insulating layer.
