Abstract: A solid electrolytic capacitor includes a bulb-metal sheet of which first face has a porous section. A dielectric film, a solid electrolyte layer, and a current-collecting layer are formed in this order on the porous section. On top of the current-collecting layer, a reinforcing plate is bonded.

The second face has another connecting terminal conductive to the bulb-metal sheet. This structure makes the capacitor thin, and allows the capacitor to increase its stress-resistance and be excellent in responsiveness to a high frequency as well as in mounting convenience.
