Title: CAPACITOR AND METHOD FOR MANUFACTURING THE SAME
Abstract:
Disclosed is a capacitor comprising a dielectric film, which has high capacitance and low equivalent series resistance. The capacitor comprises a conductive base (2) composed of a plating film having a specific surface area of not less than 100 mm2/mm3, a dielectric film (3) formed along the surface of the conductive base (2), and an opposing conductor (4) which is so formed as to face the conductive base (2) through the dielectric film (3). The plating film constituting the conductive base (2) is formed by electrolytic plating or electroless plating, and may have a porous form, wire-like form or broccoli-like form.
