In a fixing portion against which an end surface of a capacitor element abuts is provided on a portion of a cathode lead frame covered with a casing resin, the distance through which external oxygen moves to reach the capacitor element is increased by the distance of the fixing portion, whereby probability of oxidation is remarkably reduced, thus oxidation hardly occurs in the capacitor element. Further, since the capacitor element can be reliably positioned by bringing its end into abutment against the fixing portion, assembly accuracy is largely improved and the capacitor can be made compact with ease.
