Patent ID: 7453683

Claim:
A chip-type aluminum electrolytic capacitor comprising: a capacitor element; a metal case having a cylindrical shape having a bottom for storing the capacitor element together with driving electrolytic solution; a sealing member including a hole to which a pair of lead wires are inserted and sealing an open end of the metal case; an insulated terminal plate that includes an insertion hole to which the pair of lead wires introduced from the sealing member are inserted and a first concave groove for storing the lead wires inserted to the hole while the lead wires being bent in an orthogonal direction and that is attached so as to be abutted with the sealing member; the first concave groove provided in the insulated terminal plate; a metal electrode buried in the first concave groove; and a second concave groove that exposes a part of the metal electrode at a side face of the insulated terminal plate and that extends from the insertion hole of the insulated terminal plate to an end section of the insulated terminal plate.
