Abstract
An electrolytic capacitor that includes a resin molded body including a stack that includes a capacitor element with an anode exposed at a first end surface, a dielectric layer on a surface of the anode, and a cathode opposite to the anode and exposed at a second end surface; a first external electrode on the first end surface and electrically connected to the anode; and a second external electrode on the second end surface and electrically connected to the cathode, wherein the first external electrode and the second external electrode each include: a resin electrode layer containing a conductive component and a resin component; and a Ni plating layer on a surface of the resin electrode layer, wherein a ratio of a thickness of the resin electrode layer to a thickness of the Ni plating layer is 5 or less.

An electrolytic capacitor comprising:
- 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;
- a first external electrode on the first end surface of the resin molded body and electrically connected to the anode;
- and
- a second external electrode on the second end surface of the resin molded body and electrically connected to the cathode,
- wherein the first external electrode and the second external electrode each include:
- a resin electrode layer containing a conductive component and a resin component;
- and
- a Ni plating layer on a surface of the resin electrode layer, wherein
- a ratio of a thickness of the resin electrode layer to a thickness of the Ni plating layer is 5 or less.
