[PROBLEMS] To provide an electrochemical cell 10 having a wide range of applicability. According to the present invention, a casing (22) of an electrically conductive material having an open end is combined with a first and a second electrode, the first electrode contacting a first current collector and a second current collector. The electrode contacts the second current collector, the terminal lead 20 is isolated from the casing, connected to one of the first and second current collectors, the conduction extension is connected to the other of the first and second current collectors, and the electrolyte By the first and second The electrodes are activated, the open end of the casing is closed by a lid 21 of electrically conductive material, and the conduction extension is trapped in the lid. |
