Solid electrolytic capacitor, anode lead connection method for the same, and production method for solid electrolytic capacitor

Abstract

A solid electrolytic capacitor capable of assuredly connecting to a bolster member is provided. A solid electrolytic capacitor having a capacitor element with an anode made of tungsten is accommodated in a box-shaped case. An anode lead is connected to an anode circuit pattern provided on a bottom wall inner surface of the box-shaped case. In a state in which the anode lead is covered by an oxide film and is in direct contact with the anode circuit pattern, a conductive material is adhered between the anode lead and the anode circuit pattern to thereby form a conductive connection layer. The anode lead and the conductive connection layer are connected via the conductive film layer. The conductive film layer is connected to the anode lead at the film removed portion in which the oxide film has been removed from the surface of the anode lead.
