PROBLEM TO BE SOLVED: To provide a compressor which neither deteriorates the lubricating characteristics of lubricating oil or hardly develops a sludge, but keeps a hard film with a high adhesion and a wear resistance. SOLUTION: The compressor includes a compression element in a sealed container to lubricate a sliding part with the lubricating oil and compresses a refrigerant. The lubricating oil is any of a mineral oil, a polyol ester, a polyvinylether and a polyalkylene glycol, and has a kinematic viscosity of 15-80 mm<SP>2</SP>/s at 40°C. The refrigerant is a carbonization hydrogen fluoride refrigerant which does not contain a chlorine in a molecule. A vane has a mixture hard film at a contact part with the roller, and the mixture hard film contains a nitride containing one or more metals selected from the group consisting of Cr, Ti, Zr, V, and Mo.
