PROBLEM TO BE SOLVED: To improve the high-frequency characteristics of an electrolytic capacitor having improved impedance and ESL characteristics at a high frequency. SOLUTION: The electrode leads having a round rods are connected to a positive electrode foil 2 and a cathode electrode foil 3 respectively and wound with a separator 4 in between to form a capacitor element 1, and the capacitor element 1 is inserted with electrolyte or after impregnation of electrolyte into a case 9 having a bottom. In the electrolytic capacitor with an opening of the case 9 sealed with a sealing member, the rod of each electrode lead has each flat face at the opposite parts, so the impedance and ESL characteristics at the high frequency can be improved.
