ABSTRACT:
A solid electrolytic capacitor includes a porous sintered body made of valve metal, and an external anode terminal used for surface-mounting. The anode terminal is offset from the center of the sintered body, as viewed in the thickness direction or first direction of the sintered body. Further, the anode terminal is spaced away from the sintered body in a second direction which is perpendicular to the first direction. Between the sintered body and the anode terminal is formed a conductive path, which is inclined with respect to both the first and the second directions. The path comes closer to the anode terminal in the first direction as it goes farther away from the sintered body in the second direction.
