<p>PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor and its manufacturing method, that improves the reliability of electric characteristics and initial characteristics, can prevent increase in internal resistance and decrease of capacitance, and can reduce time required for manufacturing. SOLUTION: The electric double-layer capacitor is equipped with activated carbon electrodes 1 and 2 of a pair of thin films where an electrolyte is impregnated, a separator 3 that is sandwiched between the inner surfaces of the activated carbon electrodes 1 and 2, and collectors 4 and 5 that collect the charge of the activated carbon electrodes 1 and 2. A groove 7 for retaining the electrolyte is formed in the activated carbon electrodes 1 and 2 and has capacity for retaining the electrolyte with the amount of dry-up presumed at use.</p> |
