Fabricating a capacitor includes performing an oxide formation operation on a sheet of material. The oxide formation operation forms an anode metal oxide on an anode metal. A thermal compression is performed on the sheet of material after the oxide formation operation is performed. The thermal compression applies thermal energy to the sheet of material while applying pressure to the sheet of material. After the thermal compression, the capacitor is assembled such that at least one electrode in the capacitor includes at least a portion of the sheet of material.

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.
