Abstract
An electrolytic capacitor that includes: a resin molded body that includes a stack including a capacitor element and a sealing resin sealing a periphery of the stack; and an anode external electrode and a cathode external electrode on an outer surface of the resin molded body. The capacitor element includes: a valve-action metal substrate having a core and a porous portion along a surface of the core. The anode external electrode includes a first electrode layer in direct contact with the core of the valve-action metal substrate. The first electrode layer includes flat particles having an aspect ratio of 2 or more, and in a cross section, a long axis direction of the flat particles is arranged in a direction along the outer surface of the resin molded body.
