PROBLEM TO BE SOLVED: To put the effect of activation forward further to its depth, by making the voltage where activation does not occur the application start voltage, and performing the charge for a long time while raising the voltage to applicable maximum voltage. SOLUTION: A polarizable electrode is activated by performing the initial charge to the polarizable electrode consisting of carbonic material which expands at application of voltage. At this time, the voltage where activation does not occur is made the application start voltage, and the charge is started. Then, the voltage is raised gradually to the applicable maximum voltage, and charge is performed for a long time, getting over the rated charge time. At this time, a long time charge is made for a long time of one hundred times theΩF seconds, which is the time constant expressed by the product of the internal resistance of the electric double layer capacitor and the capacitance or over, or three times the rated charge time or over. As a result, the effect of activation advances uniformly to its depth, thus an electrolytic double layer capacitor which has large capacitance and is low in leak currents is manufactured.
