Patent ID: 7184257

Claim:
A solid electrolytic capacitor comprising: a capacitor element including a plurality of anodes and a cathode; a board having a first principal surface on which the capacitor element is mounted, and a second principal surface opposing the first principal surface; a plurality of anode lead conductors and a cathode lead conductor provided on the first principal surface, each of the anode lead conductors being electrically connected to a respective one of the anodes, and the cathode lead conductor being electrically connected to the cathode; and a plurality of anode lands disposed on the second principal surface at positions corresponding to respective anode lead conductors and a plurality of cathode lands disposed on the second principle surface at positions corresponding to the cathode lead conductor, the board including at least either a first conductive portion passing through the board to electrically connect each of the anode lead conductors to a respective one of the anode lands or a second conductive portion passing through the board to electrically connect the cathode lead conductor to the cathode lands, wherein the capacitor element further includes a support shaped in a thin rectangular plate and made of a valve metal, the support having a plurality of protrusions as the plurality of the anodes, the support having opposite principal surfaces covered with a continuous, electrically insulating film, and the cathode being provided on the insulating film, wherein the plurality of the anode lead conductors are provided on the first principal surface of the board, and wherein the cathode lead conductor has a first portion placed under the support and a plurality of second portions protruding from the first portion, the first portion being electrically connected to the cathode, and the second portions and the anode lead conductors being arranged alternately.
