Patent ID: 7149077

Claim:
A solid electrolytic capacitor with face-down terminals, comprising: a capacitor element including a dielectric, an electrolyte, and a cathode layer formed in order on a surface of a porous sintered body made of a valve-action metal and having an anode lead drawn out therefrom; an anode terminal having one end connected to said anode lead and another end serving as an external connection terminal; a cathode terminal disposed so as to face said anode terminal and having one end electrically connected to said cathode layer of said capacitor element and another end serving as an external connection terminal; and a casing resin which covers said capacitor element, such that said anode terminal has, as exposed surfaces, a mount surface for mounting onto a board and a first external end surface substantially perpendicular to said mount surface, and such that said cathode terminal has, as exposed surfaces, a mount surface for mounting onto the board and a second external end surface substantially perpendicular to said mount surface; wherein said anode terminal comprises: an exposed surface recessed from said first external end surface and having plating applied thereto; a stair-shaped portion, which includes an upper-stair portion connected to said anode lead and formed on a side of the anode terminal where said capacitor element is located, opposite to a side of said first external end surface, and which includes a lower-stair portion having said mount surface as a bottom surface thereof; and an engaging portion which is formed at a side wall of said stair-shaped portion for engagement with said casing resin, and which comprises one of a projecting portion and a cut-out portion.
