    Abstract: A solid electrolytic capacitor includes a capacitor element, an anode lead frame, a cathode lead frame, and an exterior member. The capacitor element includes an anode part and a cathode part. The cathode lead frame includes a cathode mount, a cathode connection part connected to the cathode mount, and a cathode terminal connected to the cathode connection part. The cathode lead frame bends in one direction at a first boundary between the cathode mount and the cathode connection part, and further bends in another direction at a second boundary between the cathode connection part and the cathode terminal. At least one of the cathode mount and the cathode terminal has a projection at an edge of the at least one of the cathode mount and the cathode terminal. The edge is at a side close to the cathode connection part. The projection projects in a first direction along which the anode part and the cathode part are aligned.

    Abstract: A solid electrolytic capacitor includes a capacitor element and an exterior body that seals the capacitor element. The capacitor element includes an anode body, a dielectric layer that is formed on the surface of the anode body, a cathode part that covers at least a portion of the dielectric layer, an anode lead with one end portion electrically connected to the anode body, and a cathode lead with one end portion electrically connected to the cathode part. The other end portion of the anode lead and the other end portion of the cathode lead are drawn out from the exterior body. The cathode part includes a solid electrolyte layer that covers at least a portion of the dielectric layer. When the solid electrolytic capacitor is subjected to a processing corresponding to mounting reflow, the amount of gas generated is 1600 μL or less.

    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.
