PROBLEM TO BE SOLVED: To provide an electrolytic capacitor that is able to improve electrostatic capacitance and decrease ESR.SOLUTION: An anode terminal 2 is embedded in one end of an anode body 1 obtained by sintering aluminium powder into a cylindrical shape, and a separator 3 is wound around the outer periphery of the anode body 1. On the outer periphery of the separator 3, a cathode body 4 having a cathode terminal at one end is arranged such that the cathode terminal is opposite the embedded side of the anode terminal 2, and the cathode body 4 is wound one time, thus obtaining a capacitor element 5. The capacitor element 5 is impregnated with an electrolytic solution and inserted into a cylindrical case 6 open at both ends thereof, and the openings of the case 6 are sealed with sealing rubbers 7, thus obtaining an electrolytic capacitor 10. |
