Abstract: An electronic component comprising a main body part including an insulating layer and a conductor layer laminated alternately. The insulating layer and the conductor layer are partially exposed on a side surface of the main body part in a direction orthogonal to a lamination direction. Also, the side surface of the main body part is provided with a metal film extending in the lamination direction to cover the insulating layer and the conductor layer exposed on the side surface.

Abstract: An electronic component including a substrate, a capacitor lower electrode disposed on the substrate, an inorganic dielectric layer disposed on the substrate to cover the lower electrode, a capacitor upper electrode disposed directly on the inorganic dielectric layer and facing the lower electrode via the inorganic dielectric layer, and a coil electrically connected to the lower electrode or the upper electrode. The upper surface of the inorganic dielectric layer is flat.
