Abstract
A capacitorincludes a capacitor elementholding solution between an anode foiland a cathode foilthat are wound up with a separatorin between, a body casefor housing the capacitor element, and a sealing memberfor sealing the body case. A part of the separatormakes contact, at a plurality of points or over an area, with the face of the sealing memberfacing the capacitor elementso as to rest on that face. The solution contains, dissolved in a lipophilic solvent, deterioration preventing agent that solidifies by oxidation. The solution is supplied through the separatorto the sealing memberand permeates the sealing member, so that a coatingresulting from the agent solidifying coats the outer face of the sealing member, leaving the solution present in the sealing member
