キャパシタ、その製造方法、および電子基板
Document Type and Number:
Japanese Patent JP4738299
Kind Code:
B2
Abstract:
A capacitor including a substrate; a conductive layer provided on the substrate and containing conductive particles; a valve metal sheet having a dielectric part formed throughout an entire surface of the conductive layer; a protection layer covering the valve metal sheet; a first electrode terminal electrically connected to the conductive layer and partially exposed from an external surface of the protection layer; and a second electrode terminal electrically connected to a surface of the valve metal sheet which is opposite to a surface of the valve metal sheet on which the dielectric part is provided, and the second electrode terminal partially exposed from the external surface of the protection layer; wherein the dielectric part is made of an oxide of a metallic material of the valve metal sheet, the dielectric part is formed with a corrugated surface on the conductive layer, and the conductive particles of the conductive layer are in contact with the corrugated surface of the dielectric part.
