Abstract
A solid electrolytic capacitor includes: a capacitor element including a sintered compact of a valve action metal, a dielectric layer, an electrolyte layer, and a cathode layer sequentially formed over a surface of the sintered compact, and an anode wire drawn out of the sintered compact; an anode terminal; a cathode terminal; and an exterior resin. The anode terminal includes a mounting portion and an upright portion. The upright portion has a trapezoidal shape. A length of a welding surface corresponding to an edge of the upright portion on the anode wire side is set to be longer than a length of the upright portion on the mounting portion side and to be longer than a width of the anode wire.
