Abstract:
1. A method for manufacturing an electrolytic capacitor, comprising the steps of: preparing a cathode foil and an anode foil; attaching electrode lead terminals in a number not less than three to said cathode foil and said anode foil, said electrode lead terminals including at least one cathode lead terminal attached to said cathode foil and at least one anode lead terminal attached to said anode foil; preparing a winding core having an axis; winding said cathode foil and said anode foil around said winding core, with said cathode foil and said anode foil overlapped each other, and removing said winding core after said step of winding, a cross section of said winding core perpendicular to said axis including an outer edge having a portion along each side of a polygon with said number of sides, said step of winding including the step of arranging the electrode lead terminals in said number on said number of sides of said polygon, respectively.
