PROBLEM TO BE SOLVED: To provide a surface-mounting thin capacitor wherein the change of product attitude can be suppressed when it is mounted and the adhesion strength of a cathode terminal can be improved. SOLUTION: The surface-mounting thin capacitor 100 uses a valve action metal anode 1 with an extended face that has a plate- or foil-like valve action, a dielectric layer is formed on its surface, and a solid electrolyte layer made of a conductive functional high molecular film 2 is formed on its central external surface. Furthermore, after a graphite layer 3 and a silver paste layer 4 are applied thereon, it is housed in a box-type mold resin case 10 provided with an external terminal. In this case, a step is made in the cathode terminal 8, and the step is covered by a resin of the mold resin case 10. Then, a cathode terminal mounting surface equivalent in area to an anode terminal 7 is formed, and it is arranged at a symmetrical position on the bottom of a product. COPYRIGHT: (C)2007,JPO&INPIT
