An ejector includes (i) a body part including a depressurizing space in which a refrigerant flowing out of a swirling space is depressurized, a suction passage that draws a refrigerant from an external, and a pressurizing space in which a jet refrigerant jetted from the depressurizing space and a suction refrigerant drawn from the suction passage are mixed with each other to be pressurized, (ii) a conical passage formation member which is arranged inside the body part, and (iii) a swirling promotion part. A nozzle passage is provided in the depressurizing space on an outer peripheral surface of the passage formation member, and a diffuser passage is provided in the pressurizing space on the outer peripheral surface of the passage formation member. The swirling promotion part includes a flow regulation plate that promotes a swirling flow of the refrigerant flowing in the diffuser passage.
