Abstract
An electrolytic capacitor in which positions of an anode terminal and a cathode terminal in a wound-type capacitor element can be fixed and consequently increase in leakage current can be suppressed and a manufacturing method thereof are provided. The electrolytic capacitor including a wound-type capacitor element having an anode terminal and a cathode terminal, a bottomed case accommodating the wound-type capacitor element, and a sealing member sealing the winding structure portion in the bottomed case, through which the anode terminal and the cathode terminal penetrate, includes a fixing member arranged between the winding structure portion and the sealing member and having openings in number not smaller than the sum of the number of anode terminals and the number of cathode terminals, the anode terminal and the cathode terminal passing through the openings, and the anode terminal and the cathode terminal being fixed by the fixing member.
