摘要： There is provided a capacitor that has excellent transient response characteristics, can be used as a distributed constant type noise filter, and can be used as a composite component having two functions of a capacitor and a distributed constant type noise filter through further reduction of an ESL of a solid electrolytic capacitor with a solid electrolytic capacitor of which capacitance is easily increased.There are prepared two capacitor element pieces 121 where both ends of an anode body of each of the capacitor element pieces form anode lead-out portions 122 and 122 and both surfaces of a middle portion of the anode body form cathode lead-out portions 123. The two capacitor element pieces 121 and 121 are stacked so that the cathode lead-out portions 123 and 123 overlap with each other and the anode lead-out portions 122 and 122 are substantially orthogonal to each other. Accordingly, a capacitor element 120 is formed. As a mounting board 141, there is prepared a mounting board 141 that includes conductors 144 and 145 and anode terminal portions 142 and a cathode terminal portion 143. The conductors 144 and 145 correspond to anode lead-out portions 122 and 122 and a cathode lead-out portion 123 of the capacitor element, and are formed on an element mounting surface of the mounting board. The anode terminal portions 142 and the cathode terminal portion 143 are formed on a mounting surface of the mounting board. The conductors 144 and 145 are connected to the anode terminal portions 142 and the cathode terminal portion 143. The capacitor element 120 is mounted on the mounting board 141, so that a solid electrolytic capacitor is formed.

摘要： A capacitor element (10) fabricated by winding an anode foil (1) and a cathode foil (2) via a separator (3) is impregnated with a 3,4-ethylenedioxythiophene and an oxidizing agent to form poly(ethylenedioxythiophene) by chemical polymerization. A nonwoven fabric composed chiefly of a synthetic fiber is used as a separator, enabling a solid electrolyte to be favorably formed without being reacted with the oxidizing agent. Preferably, the capacitor element is dipped in water at 80 to 100° C. for 1 to 20 minutes to dissolve and remove the binder in the separator in order to preclude adverse effects on the electric characteristics caused by the binder. The oxidizing agent is used at a concentration in excess of 40% by weight with respect to the solvent, so that the degree of polymerization is high and a dense and homogeneous solid electrolytic layer is formed. To form the electrolytic layer, the capacitor element is impregnated with a monomer solution prepared by mixing 3,4-ethylenedioxythiophene and a volatile solvent at a volume ratio of 1:1 to 1:3. Then, the capacitor element is heat-treated and impregnated with a solution of oxidizing agent to form a dense and homogenous solid electrolytic layer.

摘要： A solid electrolytic capacitor with a high voltage resistance property and a method of manufacturing the same is disclosed. The solid electrolytic capacitor is formed including an electrolyte layer on an anode electrode formed of a metal oxide dielectric by a polymerization reaction in which the polymerizable monomer or the monomer solution is mixed with an oxidant, wherein a Lewis base having a steric hindrance group with a nitrogen atom or a Lewis base having a hydrophilic radical with a nitrogen atom is adhered to a surface of the dielectric or incorporated in the electrolyte layer.
