A vacuum arc deposition apparatus includes arc power sources having cathodes connected to both ends of an evaporation source; exciting coils disposed at positions axially outwardly far from both the ends of the evaporation source so as to be coaxial with the evaporation source; and coil power sources independently connected to the exciting coils. In this apparatus, each of the coil power sources is capable of controlling the exciting current in such a manner that the film thickness and the consumption of the evaporation source are suitably distributed. Moreover, an arc containment device of the vacuum arc deposition apparatus includes an arc containment body having a diameter substantially the same as that of a cylindrical evaporation source, which is disposed at one end portion of the evaporation source.

A vacuum evaporator according to the present invention comprises a vacuum chamber, a rod-like evaporation source provided to be liftable into and out of the vacuum chamber, and a work support means for supporting, relative to the evaporation source lowered into the vacuum chamber, works W arranged to surround the evaporation source. The vacuum chamber is formed of a fixed chamber part and a movable chamber part provided connectably to and disconnectably from the fixed chamber part and mounted with the work support means. Either one movable chamber part is horizontally moved and connected to the fixed chamber part in the state where the evaporation source is raised and retreated out of the vacuum chamber to perform vacuum evaporation treatment. According to such a structure, the maintenance of the vacuum evaporator can be performed without raising or lowering the lower plate or taking out the work support means from the vacuum chamber.
