<p><P>PROBLEM TO BE SOLVED: To miniaturize a solid electrolytic capacitor used for various kinds of electronic equipment, and to increase its capacity. <P>SOLUTION: The solid electrolytic capacitor has: an element 10 formed by winding an anode foil 1 and a cathode foil 2 while a separator 3 is interposed between them; and a solid electrolyte 4 provided between the anode foil 1 and cathode coil 2 of the element 10 and is made of a conductive polymer. The solid electrolytic capacitor has a configuration where the anode foil 1 comprises a base material made of valve action metal foil and the vapor-deposited layer of the valve action metal formed on the surface of the base material by vapor deposition. In the vapor-deposited layer, a mode of a void diameter is 0.02-0.10μm, and the thickness (both surfaces) of the vapor-deposited layer is 20-80μm, thus miniaturizing the solid electrolytic capacitor by thinning and increasing its capacity. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
