Abstract:
A solid electrolytic capacitor comprising: a capacitor element comprising a substrate comprising a valve-acting metal having a dielectric film layer on the surface thereof, the substrate having end parts, an anode part assigned to one end part of said substrate, an insulating part comprising an insulating layer of a predetermined width provided circumferentially on the substrate in contact with said anode part, and a cathode part comprising a solid electrolytic layer and an electroconducting layer stacked in sequence on said dielectric film layer over an area other than said anode part and said insulating part,an anode-side lead frame bonded to said anode part and a cathode-side lead frame bonded to said cathode part of said capacitor element, and a resin sealing that seals said capacitor element, wherein the capacitor element and the lead frames are bonded such that the end part of said insulating layer on the side of said cathode part and the endmost part of said cathode-side lead frame in said capacitor element are spaced apart at a distance and the distance is from {fraction (1/20)} to &frac13; of the length of the cathode part, and wherein the endmost corner part of said cathode-side lead frame is chamfered in a board thickness direction.
