A solid electrolytic capacitor includes a capacitor unit having a cathode frame coupled to a cathode part of a capacitor element, and anode frames formed at the opposite sides of the capacitor unit sandwiching a cathode frame, and coupled to an anode part of the capacitor element. Flat parts provided at the opposite ends of anode terminals are coupled to the anode frames. A flat part provided in the center of a cathode terminal is coupled to the cathode frame. The capacitor unit is covered with coating resin. The solid electrolytic capacitor has a simplified structure and a lower ESL.
