PROBLEM TO BE SOLVED: To suppress the applied quantity of a solid lubricant and to reduce manufacturing costs by forming a thin film with the solid lubricant only on a necessary part corresponding to the load characteristic of a shaft, by printing at a sliding part of a refrigerant compressor. SOLUTION: A scroll compressor has a compression mechanism in a hermetically closed container. The compression mechanism has a fixed scroll, a turning scroll and an Oldham's coupling and is driven through a turning drive shaft 16. In this case, a thin film 99 with a solid lubricant is formed at the turning drive shaft 16, and the thin film 99 is formed by printing. That is, a recessed plate is filled with ink with the solid lubricant, and a pad formed out of silicone rubber is pressed to the recessed plate to transfer the ink with the solid lubricant to the pad. The pad to which the ink with the solid lubricant is stuck, is pressed to the turning drive shaft 16, and the turning drive shaft 16 is rotated to form the thin film 99 of ink with the solid lubricant, on the surface of the turning drive shaft 16.
