Abstract: An electrolytic capacitor includes a capacitor element, a lead member electrically connected to the capacitor element, an outer packaging member in which the capacitor element and a part of the lead member are sealed, and a heat barrier layer that covers at least a part of the outer packaging member. The heat barrier layer has an electrical insulation property, and contains at least one of metallic oxide and metal hydroxide.

Abstract: A solid electrolytic capacitor includes an element stack, an anode terminal, a cathode terminal, and an exterior member. The element stack includes a plurality of capacitor elements stacked on each other, and a conductive material interposed between two adjacent capacitor elements in the plurality of capacitor elements. Each of the plurality of capacitor elements includes an anode part and a cathode part, and the conductive material is disposed on the cathode part. The anode terminal is connected to the anode part. The cathode terminal is connected to the cathode part via a conductive paste. The cathode terminal has a facing surface facing a tip end of the element stack with a gap interposed between the facing surface and the tip end, and at least a part of the gap is filled with a sealing material.

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.
