    摘要: A manufacturing method includes forming a dielectric part by oxidizing an entire first surface of a valve metal sheet; forming a through hole in the valve metal sheet in which the dielectric part is formed; applying an adhesive conductive material to a surface of a substrate; attaching the valve metal sheet in which the through hole is formed, to the substrate so that the first surface contacts the conductive material on the substrate surface; forming a conductive layer by curing the conductive material; forming a protection layer which covers a second surface of the valve metal sheet which is opposite to the first surface of the valve metal sheet; forming openings in the protection layer, so that the conductive layer in the through hole and the second surface of the valve metal sheet are partially exposed from the openings; and filling up the openings in the protection layer with another conductive material to form electrode terminals.
