A refrigerant compressor is provided to make a high load part having high face pressure such as a crank-main bearing with a carbon bearing impregnated with metal for securing the resistance against wear or adhesion in the boundary lubrication state, and to make a motor-main bearing by winding a plate element for reducing the manufacturing cost. A refrigerant compressor includes a main bearing part(6C) formed of a crank-main bearing(6C1) and a motor-main bearing adjacent(6C2) to the crank-main bearing. The crank-main bearing is made of carbon bearings in which pores of a carbon base element containing graphite is impregnated with metal. The motor-main bearing is made of winding bush formed by winding a plate element.
