Abstract: An electrolytic capacitor includes a capacitor element having bottom surface B and upper surface T 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 B, 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 E each being along a direction in which the anode lead extends. Each of the two cathode anchor portions includes a cathode upright portion rising from corresponding one of two end sides E of the cathode terminal toward upper surface T, and a first extension portion and a second extension portion extending from the cathode upright portion.

Abstract: An electrolytic capacitor includes a bottom surface and a top surface, and includes a capacitor element including an anode lead, an anode lead terminal and a cathode lead terminal each electrically connected to the capacitor element, and exterior resin 101. At least one of the anode lead terminal or the cathode lead terminal includes a terminal part exposed at the bottom surface, and two anchor parts each extending from the terminal part and embedded in the exterior resin. The terminal part includes a side end along a direction in which the anode lead extends. Each of the two anchor parts includes an upright part rising from the side end of the terminal part toward the top surface, and an extending part bending and extending from an upper end of the upright part.

Abstract: An electrolytic capacitor includes a capacitor element having a bottom surface and an upper surface, an anode lead terminal, and outer packaging resin. The electrode lead terminal includes a terminal portion and two anchor portions. The terminal portion has a principal surface exposed from the bottom surface, and has an end side along a longitudinal direction of the anode lead. Each of the two anchor portions includes an upright portion that rises from an end side of the terminal portion toward the upper surface. The upright portion has a first region exposed from the bottom surface in a vicinity of a boundary with the end side, the first region has an inclined surface continuous with the principal surface of the terminal portion, and the inclined surface is inclined to form an obtuse angle with the principal surface of the terminal portion.
