Abstract:
An electrolytic capacitor that includes a resin molding that includes a capacitor element including an anode, a dielectric layer, and a cathode, a sealing resin sealing the capacitor element; a first external electrode on a first end surface of the resin molding; and a second external electrode on a second end surface and connected to the cathode exposed at the second end surface of the resin molding, wherein when viewed in a thickness direction perpendicular to the length direction, the anode includes a first anode region having a first outer edge exposed at the first end surface and connected to the first external electrode, and a second anode region having a second outer edge positioned closest to the second external electrode in the length direction, and a length of the first outer edge is greater than a length of the second outer edge in a width direction.
