1. An electrolytic capacitor including a bottom surface, a front surface rising from the bottom surface, and a rear surface opposite to the front surface, the electrolytic capacitor comprising:
a capacitor element including a first end surface facing the front surface;
an anode lead terminal and a cathode lead terminal each electrically connected to the capacitor element; and
an exterior body disposed around the capacitor element, wherein:
the capacitor element includes an anode lead protruding from the first end surface toward the front surface,
the anode lead terminal includes an anode terminal part exposed on the bottom surface, and a first upright part rising from the anode terminal part,
the first upright part includes two exposed parts, a lower part connecting lower ends of the two exposed parts, and a bent part extending from the lower part between the two exposed parts, the two exposed parts being connected to the anode terminal part and exposed on the front surface, the bent part having a recess at a tip of the bent part,
the bent part is bent toward the first end surface so that the recess is disposed in the exterior body,
a tip part of the bent part where the recess is formed extends substantially in a direction perpendicular to a surface of the anode terminal part, and
the anode lead is connected to the recess of the bent part.
