Patent ID: 8149584

Claim:
An electronic component, buried so as to be sandwiched between a first resin substrate and a second resin substrate, comprising: a supporting substrate, the supporting substrate including a mounting face which faces the first resin substrate; an opposing face which opposes the mounting face and faces the second resin substrate; and at least one pair of side faces, which intersect with the mounting face and the opposing face, the at least one pair of side faces being in contact with the second resin substrate; a dielectric film provided on the opposing face of the supporting substrate; and an electrode provided on an upper face of the dielectric film, wherein an angle θ made between at least a portion of the side faces and the mounting face at a line of intersection of the mounting face and the portion of the side faces is 0°<θ<89°, and the supporting substrate is a metal foil of Cu, Ni, Al, or a metal foil comprising one or more of these metals, or comprises a structure having a metal electrode layer of Cu. Ni, Al or a noble metal, or a metal electrode layer comprising one or more of these metals, on a Si or ceramic substrate.
