Abstract:
An electrolytic capacitor includes a capacitor element having bottom surface and upper surface and including an anode lead, a cathode lead terminal, and outer packaging resin. The cathode lead terminal includes a cathode terminal having an exposed surface exposed from bottom surface, and two cathode anchor portions each extending from the cathode terminal to be embedded in the outer packaging resin. The cathode terminal has two end sides each being along a longitudinal direction of the anode lead. Each of the two cathode anchor portions includes a cathode upright portion rising from corresponding one of two end sides of the cathode terminal toward upper surface, a first extension portion extending from the cathode upright portion, and a second extension portion extending from the first extension portion.
