According to one embodiment, a compressor uses R-32 as a refrigerant and contains a refrigerating machine oil. A liquid mixture of the refrigerating machine oil and the refrigerant is separated into two layers at a content of the refrigerating machine oil within a range of 10 to 40% by mass and a temperature within a range of -40 to 60°C, and is compatible at a content of the refrigerating machine oil of not more than 5% by mass and a temperature within a range of 20 to 40°C and also at a content of the refrigerating machine oil of not less than 55% by mass and a temperature within a range of 20 to 50°C.
