Abstract:
1. A chip-type solid electrolytic capacitor having a four-terminal structure, the chip-type solid electrolytic capacitor comprising: a laminated capacitor element in which a plurality of plane capacitor elements, each having an anode electrode and a cathode electrode, are laminated such that the anode electrodes are disposed alternately in opposite directions; a pair of anode lead terminals bonded to the anode electrodes in opposite directions; a cathode lead terminal bonded to the cathode electrodes, the cathode lead terminal having a pair of cathode terminals disposed in two directions perpendicular to the pair of anode lead terminals; and coating resin covering an entire circumference of the laminated capacitor element except for parts of the anode lead terminals and the cathode lead terminal which are left exposed; wherein, the anode lead terminals and the cathode lead terminal are exposed from the coating resin on a bottom face of the chip-type solid electrolytic capacitor; a central section of the cathode lead terminal is thinner than both edges thereof, and this central section is covered with the coating resin; and a pair of cathode terminals which are exposed sections of the cathode lead terminal and a pair of anode terminals which are exposed sections of the anode lead terminals are disposed on the bottom face.
