To provide an ejector cycle to reduce any heat losses on the low-pressure side.
Because at least an evaporator 30 and a vapor-liquid separator 50 are accommodated in a same casing 80, the vapor-liquid separator 50 and the evaporator 30 are close to each other, heat absorption by a liquid phase refrigerant flowing out of the vapor-liquid separator 50 from the atmosphere can be suppressed, heat losses can be reduced, and also any pressure losses generated in a refrigerant passage from the vapor-liquid separator 50 to the evaporator 30 can be reduced. Thus, the heat losses and the pressure losses generated in the total ejector cycle is reduced, the coefficient of performance of the ejector cycle is improved, and the ejector cycle is miniaturized.
