Abstract: Provided is an electrolytic capacitor including: a capacitor element including an anode body, a dielectric layer formed on the anode body, a solid electrolyte layer formed on the dielectric layer, and a cathode layer formed on the solid electrolyte layer; lead terminals each connected to the anode body and the cathode layer; and a packaging member covering at least part of the capacitor element. The packaging member includes a side wall that is electrically conductive, and a bottom face, with at least one of the lead terminals partially exposed from the bottom face. An insulating member is interposed between a first end of the side wall and the lead terminal exposed from the bottom face, the first end being near the bottom face.

Abstract: A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode foil including a base material part and a porous part disposed on a surface of the base material part, a dielectric layer disposed on at least a part of a surface of the anode foil, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The anode foil includes an anode section on which the solid electrolyte layer is not disposed, a cathode formation section on which the solid electrolyte layer is disposed, and a separation section located between the anode section and the cathode formation section. A first insulating material is disposed on a surface of the porous part in the separation section. And at least a part of a region of the porous part that is covered with the first insulating material includes a second insulating material.
