PROBLEM TO BE SOLVED: To achieve further low ESL of a chip-type solid electrolytic capacitor to be used for various kinds of electronic equipment. SOLUTION: The solid electrolytic capacitor consists of a capacitor element 1 formed such that each of anodes having anode electrode portions of the same profile and substantially the same area protruding on opposite sides is separated into the anode electrode portion and a cathode forming portion by an insulating portion, and a solid electrolytic layer and a cathode layer are formed on the cathode forming portion to form a cathode electrode portion; anode and cathode terminals 7, 8 to which anode/cathode electrode portions of the capacitor element 1 are connected; and an armoring resin 10 covering the capacitor element 1. The capacitor element 1 is alternately laminated so that the anode electrode portions may not be superimposed on the same position. With this configuration, since the anode/cathode portions can be closely disposed on the same line in the state of the capacitor element 1 and a multi-terminal structure in which the anode and cathode terminals 7, 8 are closely disposed on each of sides, currents flowing between the anode and cathode terminals 7, 8 are canceled to remarkably reduce ESL. Thus, large capacity can be achieved. COPYRIGHT: (C)2008,JPO&INPIT
