PURPOSE:To provide a separator which has a heat-resistant property and an affinity with an electrolytic solution by a method wherein a polymer film which has been impregnated with a fluorine-based surface-active agent by making use of pores in a fluorine-based polymer porous film is manufactured as a fluorine-based porous polymer film and a multilayer body in which a paper base material or a sheet of manufactured paper has been laminated is used for the polymer film. CONSTITUTION:A separator 7 for a capacitor is composed of a multilayer body obtained by using a paper base material or a sheet of manufactured paper and a special polymer film. The special polymer film is a polymer film A which has been impregnated with a fluorine-based surface-active agent by making use of pores in a fluorine-based polymer porous film. Then, the separator is manufactured in such a way that an adhesive layer is formed on the surface of the paper base material and that the polymer film A is bonded to, and formed in multilayer, the face of the adhesive layer so as to be integrated. The separator 7 for the capacitor is sandwiched between, and held by, both electrode foils as an anode foil 1 and a cathode foil 2. Then, this assembly is wound to be a tubular shape, lead wires 3 are connected respectively to the anode foil 1 and the cathode foil 2, and a capacitor element 4 is manufactured. |
