PROBLEM TO BE SOLVED: To provide a compressor which is suitable for mixed refrigerant having high saturation pressure and has high reliability by dividing a closed case into a cylindrical main body case part and an end plate part to facilitate machining the closed case, and improving the case compressive strength. SOLUTION: This compressor has a motor part 21 and a compression machine part 22 stored in the closed case 51, and uses mixed refrigerant obtained by mixing HFC 32 of 40-60 wt.% and HFC 125 of 60-40 wt.% as a refrigerant. The closed case 51 of the compressor is formed by three pieces, those are, the cylindrical main body case part 51a, and the end plate parts 51b, 51c on both sides of the main body case part 51a. The main body case part 51 is formed by cylindrically bending a case member made by a flat plate-like SPH material to form one mating part, and joining the mating part.
