Patent ID: 8320106

Claim:
A lower-face electrode type solid electrolytic multilayer capacitor comprising: a solid electrolytic multilayer capacitor element having layered capacitor elements, each of the capacitor elements having an anode portion and a cathode portion, the anode portion being one side of an anode body having a valve action metal that is linear shape, foil shape, or plate shape, and the cathode portion having a dielectric layer, a solid electrolyte layer, a graphite layer, and a silver paste layer formed in series on a surface of the other side of the anode body separated by an insulating resin layer; and an electrode substrate having an element connecting electrode terminal on one side of the electrode substrate and a mounting electrode side terminal on the other side of the electrode substrate, the element connecting electrode terminal being electrically connected to the anode portion or the cathode portion of the solid electrolytic multilayer capacitor element, the mounting electrode side terminal being electrically connected to a circuit board, and the element connecting electrode terminal and the mounting electrode side terminal being electrically connected each other; wherein the solid electrolytic multilayer capacitor is packaged by a covering resin such that the mounting electrode side terminal of the electrode substrate is exposed, an electrode substrate cutting portion is formed at an edge face of the electrode substrate on which the element connecting electrode terminal and the mounting electrode side terminal are arranged, a side surface of the electrode substrate cutting portion is plated so that the element connecting electrode terminal is electrically connected to the mounting electrode side terminal, and a covering resin cutting portion is formed on an edge face of the covering resin in a staircase pattern so that the electrode substrate cutting portion is surrounded by the covering resin cutting portion.
