Abstract: A refrigerant compressor includes a compressor mechanism part 2, and a motor and a crank shaft 101 for driving the compressor mechanism part, in a sealed case 100, and includes sliding bearings 103, 104, and 105 at least either in an engagement part between the compressor mechanism part and the crank shaft or in a rotation support part of the crank shaft. Further, an unleaded resin impregnation material is used for at least one of the sliding bearings, the crank shaft is made of a ferrous material, and a hard carbon film including hydrogen is formed on a part of the crank shaft sliding with the sliding bearing using the unleaded resin impregnation material.
