<p>A film forming method for a compressor and a part of the compressor to be formed with a film are disclosed. A paint container (36) is arranged above a rotary holding mechanism (34) with a swash plate (15) of the compressor mounted thereon. A lubrication paint (37) in the paint container (36) is dripped on the end surface (152) of the swash plate (15) through a dripping unit (38). The swash plate (15) is rotated at high speed by the operation of a motor (M) so that the surplus portion of the lubrication paint (37) on the end surface (152) is removed by centrifugal force. The lubrication paint (37) remaining on the end surface (152) with the surplus portion thereof removed by centrifugal force has a uniform film thickness. <IMAGE></p>
