ABSTRACT:
The capacitor element includes as an anode an aluminum foil in the form of a thin plate, an oxide layer formed as a dielectric on the surface of the anode, and a conductive polymer layer formed as a cathode on the dielectric. The capacitor is formed by drawing terminals in arrays from the capacitor element. On the upper side of the capacitor element is provided an embossed copper foil11for suppressing deformation of the capacitor element. The anode terminals and the cathode terminals are drawn to the lower side of the capacitor element. The anode terminals and the cathode terminals are alternately formed at the same pitch in the x-direction and the y-direction, so that the heteropolar terminals are disposed at the adjacent positions with respect to any one of the terminals.
