The condenser contains a film layer composed predominantly of a vinylidene fluoride resin; and a coating layer composed of a mixture of the vinylidene fluoride resin and a polymer substantially incompatible with the vinylidene fluoride resin and having a critical surface tension of 30 dyn/cm or higher.
<??>With the condenser components as set forth hereinabove can render the condenser compact without decreasing the performance inherent in the polyvinyl fluoride resin.
