A liquid recovery device includes: an outer pipe that includes an introduction portion into which a gas-liquid two-phase fluid is introduced; an inner pipe disposed inside the outer pipe at a position where the introduction portion is extended to a downstream side in a flow direction of the gas-liquid two-phase fluid; a double pipe portion that includes a clearance part provided between an inner side of the outer pipe and the inner pipe at a downstream side of the outer pipe in the flow direction; a communication hole that communicates the inner side of the inner pipe with the clearance part; and a drainage portion connected to the clearance part to discharge the liquid-phase fluid flowing into an interior of the clearance part.
