1. A tantalum capacitor comprising:
a tantalum body including tantalum powder and having a tantalum wire exposed to one end surface of the tantalum body;
a molded portion having two surfaces opposing each other in a first direction, two surfaces opposing each other in a second direction, and two surfaces opposing each other in a third direction, the two surfaces opposing in the third direction being first and second surfaces, the two surfaces opposing in the second direction being third and fourth surfaces, the two surfaces opposing in the first direction being fifth and sixth surfaces;
an anode lead frame exposed to the second surface of the molded portion and electrically connected to the tantalum wire; and
a cathode lead frame spaced apart from the anode lead frame and exposed to the second surface of the molded portion,
wherein the anode lead frame includes a first connection portion, a first lead portion, a cut surface and a first bent portion, and the first bent portion forms an angle of inclination, ranging from 70° or more to 80° or less, with respect to the first connection portion, the first bent portion being inclined toward a side of the tantalum body,
wherein the first bent portion comprises a portion of the anode lead frame removed from the first lead portion so as to form the cut surface and an end portion contacting the tantalum wire,
wherein the anode lead frame includes a bending portion disposed on an end of the first bent portion, and the bending portion and the tantalum wire are in contact with and connected to each other, and
wherein the bending portion extends from the end of the first bent portion in a direction substantially parallel to an elongation direction of the tantalum wire.
