A solid electrolytic capacitor of the present invention includes a
capacitor element with an anode element and a cathode layer, having an
anode lead member planted on one end surface of the anode element, an
anode terminal connected to the anode lead member, a platy cathode
terminal placed on a reverse surface of the capacitor element and
connected to the cathode layer, and an enclosure resin part enclosing the
capacitor element, a part of the cathode terminal and a part of the anode
terminal being exposed from a bottom surface of the enclosure resin part.
At least the cathode terminal has formed thereon a plurality of
projections projecting in a position apart from a reverse surface of the
enclosure resin part in a direction along the reverse surface.
