Abstract
A capacitor includes a capacitor element having a predetermined liquid preparation held between a pair of electrodes facing each other across a separator, a body case for housing the capacitor element, and a sealing member made of rubber for sealing seals the body case. A supplying portion is provided in contact with the sealing member to supply the liquid preparation held in the capacitor element to the sealing member. The liquid preparation has a lipid-soluble sealing member deterioration preventing agent dissolved in a lipophilic solvent. The sealing member deterioration preventing agent supplied by the supplying portion to the sealing member permeates the sealing member. The ratio by weight of the sealing member deterioration preventing agent in the sealing member to the sealing member is 0.1% by weight to 25% by weight.
