する為と考えられる。(Function) The effect of improving the voltage resistance of the (hydro, hydrocarbyl, or hydrocarpyroyl), (polyoxyethylene or polyoxypropylene), cholesteryl ether compounds used in the present invention is that of electrolytic filtrate and capacitors. This is thought to be because the above-mentioned compounds as nonionic surfactants form an appropriate micelle layer at the interface of the dielectric aluminum oxide film.
