1. A solid electrolytic capacitor comprising a capacitor element, an outer anode terminal, an outer cathode terminal and an outer mold, wherein:
the capacitor element has an anode lead wire, an anode body and a cathode layer;
the capacitor element has an upper surface and a lower surface in an up-down direction;
the outer anode terminal is connected with the anode lead wire;
the outer cathode terminal is connected with the cathode layer;
the outer cathode terminal and the outer anode terminal are positioned away from each other in a predetermined direction perpendicular to the up-down direction;
the outer cathode terminal has an upper portion, a lower portion and a connecting portion;
the upper portion is positioned above the upper surface of the capacitor element in the up-down direction;
the lower portion is positioned below the lower surface of the capacitor element in the up-down direction;
the connecting portion connects the upper portion and the lower portion with each other;
one of the upper portion and the lower portion is longer than a remaining one of the upper portion and the lower portion in the predetermined direction;
the outer mold covers the capacitor element so that each of the outer anode terminal and the outer cathode terminal is partially exposed to an outside of the solid electrolytic capacitor;
the upper portion has an upper surface and a lower surface in the up-down direction;
the lower surface of the upper portion is larger than the upper surface of the upper portion;
the lower portion has an upper surface and a lower surface in the up-down direction; and
the upper surface of the lower portion is larger than the lower surface of the lower portion.
