An ejector-type refrigeration cycle (10) equipped with an ejector module (13) in which a gas-liquid separation device is integrally formed. The length of an inlet pipe (15d) connecting a liquid-phase refrigerant outflow port (31c) of the ejector module (13) and a refrigerant inlet of an evaporator (14) is less than the length of an intake pipe (15c) connecting a gas-phase refrigerant outflow port (31d) of the ejector module (13) and the intake port of a compressor (11). Thus, the absorption of heat in the engine room by the liquid-phase refrigerant passing through the inlet pipe (15d) is suppressed, and a reduction in the cooling performance achieved by an evaporator (14) is suppressed.
