Provided is a solid electrolytic capacitor (20) that includes: a capacitor element including an anode(1) that contains tantalum as a principal component and is formed with a porous sintered body, an anode lead (2) that contains niobium as a principal component and has one end (2a) buried in the anode (1) and the other end (2b) protruded from the anode (1), a dielectric layer (3) that is provided on a surface of the anode (1) and a part of a surface of the anode lead (2), and a cathode layer (6) provided on the dielectric layer (3); an anode terminal (7) electrically connected to the other end (2b) side of the anode lead (2); a cathode terminal (9) electrically connected to a cathode layer (5); and a resin package (11) covering the surfaces of the capacitor element, a part of the anode terminal (7), and a part of the cathode terminal (9). The solid electrolytic capacitor is characterized in that the resin package (11) has a linear expansion coefficient that is greater than any one of linear expansion coefficients of the anode (1), the anode lead (2), the anode terminal (7), and the cathode terminal (9). |
