Abstract
An electrolytic capacitor having a capacitor element which includes a plurality of foils, and having also an electrolyte, wherein the plurality of foils and the electrolyte are contained in a cylindrical case having on one of its end surfaces a pair of lead terminals to connect to the capacitor element and on another of its end surfaces an explosion preventive vent is electrically aged. The electrolytic capacitor is placed onto a support table so that the capacitor's end surface having the lead terminals is not below the capacitor's end surface having the explosion preventive vent. Each one of the pair of lead terminals is connected to a respective one of a pair of electrode sections. An electric voltage is then applied across the pair of lead terminals through the pair of electrode sections.
