1. A method of producing an electrolytic capacitor, the method comprising:
preparing a resin molded body having opposed first and second end surfaces, the resin molded body including a stack that includes a capacitor element with an anode exposed at the first end surface, a dielectric layer on a surface of the anode, and a cathode opposite to the anode and exposed at the second end surface, and a sealing resin that encloses the stack;
screen printing an electrode paste on at least one of the first end surface and the second end surface simultaneously with wrapping the electrode paste on at least one of a bottom surface and a top surface of the resin molded body;
thermally curing the electrode paste at a temperature of 150° C. to 200° C. on: (1) the first end surface and at least one of the bottom surface and the top surface to form an integrally connected first external electrode on the first end surface and the at least one of the bottom surface and the top surface, and/or (2) the second end surface and at least one of the bottom surface and the top surface to form an integrally connected second external electrode on the second end surface and the at least one of the bottom surface and the top surface.
