PROBLEM TO BE SOLVED: To provide a chip like solid electrolytic capacitor which has a low ESR and a low initial failure rate. SOLUTION: This capacitor is the chip like solid electrolytic capacitor such that a plurality of solid electrolytic capacitor elements of which the cathode portions are formed by laminating a dielectric oxide film layer, a semiconductor layer, and a conductor layer in order on a remnant surfaces except anode plate portions on one end of the anode plate bases comprising sintered bodies of valve action metal or conductive oxide, or connecting members of the sintered bodies and metal wires, are horizontally parallelly tightly placed and held, and joined so as to contact the anode plate portions or metal wire portions and the cathode portions to the lead frames on points of a pair of lead frames which are opposed to each other, and such that they are then sealed by a resin except external terminals of the lead frames. In the capacitor, the volume ratio of one of sintered bodies except the anode plate portions to the chip volume is constituted to be in 0.042-0.110. The present invention includes an electronic device using the chip like solid electrolytic capacitor. COPYRIGHT: (C)2005,JPO&NCIPI
