Abstract
When forming a film on a work, such as a lamp holder, the work is not set in a film-forming chamber as in the prior art, but a film is formed thereon by using a mold, thereby simplifying the film formation work. A movable mold is matched to a fixed mold in a state where a vacuum deposition apparatus, the film-forming element, is provided in the fixed mold and the work is supported in the movable mold. Next, film formation is carried out with the film-forming space in a vacuum state. Thereafter, the movable mold is opened, wherein the film formation work on the work surface using molds can be carried out with a series of processes.
