Abstract
A hoop metal lead frame ( ) having, solid electrolytic capacitor elements ( ) on its terminal sections ( ) is provided with a crosspiece ( ) bridging both sides in terms of the width direction disposed along the length direction in a region between the capacitor elements ( ), one crosspiece for two capacitor elements ( ). The metal lead frame ( ) is placed on a molding die so that the region without having the crosspiece is locating at the sub runner ( ), which has branched out from the main runner ( ). The capacitor elements ( ) are encapsulated with a molding resin injected through the sub runner ( ). Since the molding resin is not covering the crosspiece ( ), the main runner portion ( ) and the sub runner portion ( ) can be severed from the metal lead frame ( ) without effecting unwanted stress on the solid electrolytic capacitors ( ). The solid electrolytic capacitors ( ) thus manufactured have a superior property in the tight hermetic sealing.
