Claim:
1. A solid electrolytic capacitor comprising: a capacitor element equipped with an anode made of tungsten, the anode including an anode lead implanted in the anode and covered with an oxide film, and the anode lead being protruded from an end face of the anode; and a box shaped case in which the capacitor element is accommodated, the box shaped case including a bottom wall inner surface to which an anode circuit pattern is provided, and the anode lead being connected to the anode circuit pattern electrically and mechanically, wherein in a state in which the anode lead is directly connected to the anode circuit pattern, between the anode lead and the anode circuit pattern, a conductive material is adhered and a conductive connection layer is formed, wherein the anode lead and the conductive connection layer are connected via a conductive film layer, and wherein the conductive film layer is connected to the anode lead at a film removed portion in which the oxide film is removed from a surface of the anode lead.
