Document Type and Number:
Japanese Patent JP6952272
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrolytic capacitor in which a leak current is reduced.SOLUTION: An electrolytic capacitor comprises: an anode body in which a dielectric layer is formed on a surface of a metal foil; and a lead member connected to the anode body. The anode body and the lead member are connected by a plurality of caulking parts in an overlapped part in which the anode body and a part of the lead member are overlapped each other. The plurality of caulking parts each includes a through-hole through which the anode body and the lead member penetrate. The shortest distance T from an end of a first through-hole nearest to an end surface on the side of the overlapped part of the anode body is twice or more the shortest distance S between both ends of the adjacent through-holes.SELECTED DRAWING: Figure 1
