CAPACITOR

A capacitor 1 includes a capacitor element 3 holding solution between an anode foil 5 and a cathode foil 7 that are wound up with a separator 6 in between, a body case 2 for housing the capacitor element 3, and a sealing member 4 for sealing the body case 2. A part of the separator 6 makes contact,...

More Information
Summary:A capacitor 1 includes a capacitor element 3 holding solution between an anode foil 5 and a cathode foil 7 that are wound up with a separator 6 in between, a body case 2 for housing the capacitor element 3, and a sealing member 4 for sealing the body case 2. A part of the separator 6 makes contact, at a plurality of points or over an area, with the face of the sealing member 4 facing the capacitor element 3 so 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 separator 6 to the sealing member 4 and permeates the sealing member 4, so that a coating 17 resulting from the agent solidifying coats the outer face of the sealing member 4, leaving the solution present in the sealing member 4.
