Solid electrolytic capacitor

A solid electrolytic capacitor comprising:

• an element stack including a plurality of capacitor elements stacked on each other and a conductive material disposed between two adjacent capacitor elements in the plurality of capacitor elements, the plurality of capacitor elements including a first capacitor element and a second capacitor element, each of the first capacitor element and the second capacitor element including an anode part and a cathode part, the conductive material being disposed on the cathode part;
• an anode terminal connected to the anode part;
• a cathode terminal connected to the cathode part via a conductive paste;
• and
• an exterior member that covers the element stack, the anode terminal, and the cathode terminal in a state where a part of each of the anode terminal and the cathode terminal is exposed, wherein:
• the first capacitor element is closest to a connection part of the cathode terminal, the connection part connecting to the element stack,
• the cathode terminal has a facing surface facing a tip end of the element stack with a gap between the facing surface and the tip end,
• in a stacking direction of the plurality of capacitor elements, which is parallel to a normal direction of an upper surface of the connection part of the cathode terminal, a height of the facing surface from the upper surface of the connection part of the cathode terminal is greater than a height of an upper surface of the first capacitor element from the upper surface of the connection part of the cathode terminal,
• the facing surface of the cathode terminal is inclined with respect to the stacking direction so that a dimension of the gap in a direction parallel to the upper surface of the connection part of the cathode terminal between the facing surface of the cathode terminal and the tip end of the element stack is increased along the stacking direction from the connection part of the cathode terminal,
• an angle formed by the facing surface and the stacking direction is less than or equal to 30 degrees,
• at least a part of the gap is filled with a sealing material, and
• the sealing material is made of a same material as the exterior member and continuous from the exterior member.
