An electrolytic capacitor includes a capacitor element, an anode lead terminal, a cathode lead terminal, and a resin outer package. The capacitor element includes an anode part and a cathode part. The anode lead terminal is electrically connected to the anode part. The cathode lead terminal is electrically connected to the cathode part, and has a first main surface and a second main surface opposite to the first main surface. The resin outer package covers the capacitor element. The cathode lead terminal includes a joint part to be joined with the cathode part. The joint part has a recess on the first main surface. In at least one cross-section cutting the recess an being perpendicular to the first main surface, a relation D1
