Abstract: A disclosed solid electrolytic capacitor element includes an anode section disposed on one end side and a cathode section disposed on the other end side. The cathode section has a pair of principal surfaces, a pair of side surfaces each connecting the pair of principal surfaces to each other and extending along a direction connecting the one end and the other end, and a first end surface connecting the pair of principal surfaces to each other and located at the other end. At least one of the side surfaces has at least one recess including a first end on the one end side and a second end on the other end side. A distance D1 between the first end surface and the second end is 0.05 L1 or more, where the L1 represents a distance between the one end and the other end.
