PROBLEM TO BE SOLVED: To increase reliability of an electrolytic capacitor by reducing a contact resistance between outgoing leads and terminals. SOLUTION: After a sealing plate 15, provided with the terminals 16 and the outgoing leads 14 extended from a capacitor element 13, are connected to each other and then the capacitor element 13 is stored in an outer jacketing case 11, the sealing plate 15 is set in an opening 11a of the outer packaging case 11 to seal the capacitor element 13, to complete an aluminum electrolytic capacitor. In this aluminum electrolytic capacitor, the outgoing leads 14 and internal terminals 16a, 16b of the terminals 16 are connected by calking, and the parts of the outgoing leads 14 and the internal terminal 16a are laser-welded.
