An electric double layer capacitor which employs a unit cell (10) comprising upper and lower noncontact metal cases (1, 2), two polarization electrodes (3a, 3b) having a surface impregnated or coated with electrolyte and attached tightly or bonded to the inner surfaces of the upper and lower metal cases (1, 2), a short circuit prevention separator (4) arranged between the two electrodes (3a, 3b), and an insulating gasket (9) fitted between the upper and lower metal cases (1, 2). The electric double layer capacitor comprises an insulating container (16), for containing the unit cell (10), having a through opening (18) in the bottom face or a bottom plate (17) and containing the unit cell (10) such that the lower surface of the lower metal case (2) of the unit cell (10) touches the upper surface of the bottom plate (17), an upper terminal (20) having one end bonded to the upper metal case (1) and the other end extending horizontally on a plane substantially identical to the lower surface of the bottom plate (17), and a lower terminal (30) provided with a first end portion (32) having one end passing the through opening (18) and bonded to the surface of the lower metal case (2) and a second end portion (34) extending horizontally on a plane substantially identical to the lower surface of the bottom plate (17). |
