Electrolytic capacitor

An electrolytic capacitor according to the present invention is provided with: a rectangular parallelepiped-shaped resin molded body provided with a laminate including a capacitor element including an anode having a dielectric layer on the surface thereof and a cathode facing the anode, and a sealing resin for sealing the periphery of the laminate; a first external electrode formed on a first end surface of the resin molded body and electrically connected to the anode exposed from the first end surface; and a second external electrode formed on a second end surface of the resin molded body and electrically connected to the cathode exposed from the second end surface, the electrolytic capacitor being characterized in that the first external electrode and the second external electrode each have: a resin electrode layer containing a conductive component and a resin component; and a Ni plating layer provided on the surface of the resin electrode layer, the ratio of the thickness of the resin electrode layer to th
