Abstract:
1. A solid electrolytic capacitor, comprising: a capacitor element having an element body with a cathode layer that forms at least a partial region of the outer circumference of the element body, and an anode lead pulled out of the element body through the outer circumference of the element body, the outer circumference of the element body being defined by a first end surface through which the anode lead is pulled out, a second end surface opposite the first end surface, and a side surface extending from the outer periphery of the first end surface to the outer periphery of the second end surface; a conductive member made of a conductive material different from that of the anode lead, and placed to face the first end surface of the element body; an electrical insulating member placed between the conductive member and the element body; and a tubular member made of a conductive material different from that of the cathode layer, wherein a first through hole through which the anode lead passes is defined in the electrical insulating member, a second through hole or a closed end hole into which a tip end portion of the anode lead is inserted is defined in the conductive member, and the tip end portion of the anode lead is press-fitted into the second through hole or joined to the inner circumference of the closed end hole, at least part of the element body of the capacitor element is arranged inside the tubular member, while the cathode layer of the capacitor element is connected through a conductive adhesive to the inner circumference of the tubular member, and an exposed surface of the conductive member forms an anode terminal surface, and the outer circumference of the tubular member forms a cathode terminal surface.
