An electrolytic capacitor comprises two lead tab terminals and a sealing rubber packing. Each of the lead tab terminals includes a boss member, a rib member and a flat member. The boss member comprises a coupling member and a large member. The diameter of the coupling member is the same as two holes in the sealing rubber packing, and the diameter of the large member is larger than the two holes. The flat member is connected to either an oxidized anode foil or a cathode foil. The coupling members of the two lead-tab terminals are inserted into the two holes in the sealing rubber packing, respectively. The large member keeps the sealing rubber packing from moving toward the flat member. Accordingly, the sealing member sealing the capacitor element into a case is kept from making contact with the capacitor element.
