An ejector refrigeration cycle device includes: a decompressor that decompresses a refrigerant heat-exchanged in a radiator; a first exterior heat exchanger that exchanges heat between the refrigerant decompressed by the decompressor and outside air; an ejector that decompresses the refrigerant flowing out of the radiator in a nozzle portion and draws another refrigerant heat-exchanged in the first exterior heat exchanger; a branch portion in which the refrigerant heat-exchanged in the radiator branches to a side of the decompressor and a side of the nozzle portion; a second exterior heat exchanger that exchanges heat between the refrigerant pressurized in the ejector and the outside air; a bypass portion that causes the refrigerant heat-exchanged in the radiator to flow to the first exterior heat exchanger while bypassing the decompressor and the nozzle portion; and an opening/closing portion that opens or closes the bypass portion.
