PROBLEM TO BE SOLVED: To provide a surface-mounting thin capacitor capable of preventing displacement when mounted on a substrate. SOLUTION: In the surface-mounting thin capacitor, a capacitor element including an oxide film serving as a dielectric layer and a conductive function polymeric molecule serving as a solid electrolyte layer is stored in an exterior case to whose bottom surface an electrode terminal for surface-mounting is formed. The oxide film is formed on a surface of an anodic body made of a foil-shaped valve action metal whose surface is extended. The exterior case consists of a case 2 opened at an upper side, and a cover 1 covering the upper side and a lateral side of the case 2. A convex part 1a projecting below than a mounting surface of an anode terminal 3 and a cathode terminal 4 is provided at four corners of the cover 1 opposed to a mounting surface of the cover 1.
