Abstract
Electrode lead terminals in a number not less than three are attached to a cathode foil and an anode foil. The electrode lead terminals include at least one cathode lead terminal attached to the cathode foil and at least one anode lead terminal attached to the anode foil. A winding core having an axis is prepared. The cathode foil and the anode foil are wound around the winding core, being overlapped each other. A cross section of the winding core perpendicular to the axis includes an outer edge having a portion along each side of a polygon with the above number of sides. Thereby, a method for manufacturing an electrolytic capacitor capable of suppressing displacement of a lead terminal can be provided.
