<p>PROBLEM TO BE SOLVED: To provide an electrochemical capacitor capable of suppressing increase in the internal resistance, while prolonging the life, by suppressing retention of gas.SOLUTION: A hybrid capacitor 1 includes an electrochemical cell 11 including a positive electrode 2, a negative electrode 3 attached to face the positive electrode 2, a cell 5 for housing the positive electrode 2 and negative electrode 3, and filled with an electrolyte 6, and a check valve 10 for discharging gas in the cell 5, and a pressurizer 12 for pressurizing the electrochemical cell 11 in the facing direction of the positive electrode 2 and negative electrode 3. The pressurizer 12 includes a pair of constraining plates 13 arranged oppositely so as to sandwich the electrochemical cell 11, and a plurality of protrusions 14 protruding from the surface of the constraining plate 13 facing the electrochemical cell 11 toward the electrochemical cell 11, and arranged at predetermined intervals each other.</p> |
