Abstract: An apparatus for physical vapor deposition comprising a vacuum casing one end of which is open; a sealing member provided at the opening of the casing; an electrode for physical vapor deposition, such as a target electrode or an electrode for heating evaporation, which is provided in the casing; and an exhaust hole for exhausting gases in the casing, which is provided at a predetermined wall portion of the casing. The apparatus may also be provided with a gas introducing hole and a bias electrode. The casing is integrally fitted to a body to be treated at the opening end portion thereof by means of the sealing member to form a vacuum chamber therein. This apparatus is compact and enables the surface treatment of a large or immovable body without moving the body.
