Abstract
A solid electrolytic capacitor comprising a capacitor element comprising a valve-acting metal substrate having on the surface thereof a dielectric film and a solid electrolytic layer provided on the dielectric film, the capacitor element provided with lead wires (lead frames), in which the bonding structure between the capacitor element and the lead frames is improved. The solid electrolytic capacitor has high strength at the bonded portion between the capacitor element and the lead frames and has excellent heat resistance and is highly reliable. Also, a method for manufacturing such a solid electrolytic capacitor is disclosed.
