ABSTRACT:
A solid electrolytic capacitor includes a capacitor element and a board mounting the capacitor element thereon. The capacitor element includes a support made of a valve metal, and an anode and a cathode provided on the support. Anode and cathode lead conductors connected to the anode and the cathode are provided on a first principal surface of the support, and anode and cathode lands are formed on a second principal surface. A conductive portion passing through the board electrically connects either the anode lead conductor to the anode land or the cathode lead conductor to the cathode land.
