A plurality of targets are disposed in parallel with, and at a given distance to, one another. In case a predetermined thin film is formed by sputtering, the occurrence of non-uniformity in the film thickness distribution and the film quality distribution can be restricted. During the time when electric power is charged to a plurality of targets (31a to 31h) which are disposed inside a sputtering chamber (11a) so as to lie opposite to the process substrate (S), and are disposed at a predetermined distance from, and in parallel with, one another, thereby forming a predetermined thin film by sputtering, each of the targets is reciprocated at a constant speed in parallel with the process substrate. Also, magnet assemblies that form tunnel-shaped magnetic flux (M) in front of each target are reciprocated at a constant speed in parallel with each of the targets. When each of the targets has reached a turning position of the reciprocating movement, the reciprocating movement of each of the targets is stopped for a predetermined period of time.
