Abstract: An oil separator includes a cylindrical first separating section having a first inner space where the refrigerant can swirl; a cylindrical second separating section disposed below the first separating section and having a second inner space where the refrigerant can swirl; an introduction tube sending the refrigerant toward an inner wall of the first separating section so that a swirl flow occurs; a delivery tube delivering the separated refrigerant; and an exhaust pipe discharging the separated refrigerant oil, the second separating section having a surface connecting the inner wall of the first separating section and an upper end of an inner wall of the second separating section and forming a step, and an angle between the surface and the inner wall of the first separating section and an angle between the surface and the inner wall of the second separating section being 90 degrees or smaller.
