Provided is a dehydrator that requires no excessively large apparatus structure and achieves cost-saving while maintaining suction efficiency at a desired level by use of suction means. A dehydratorfor separating water from a target liquidincludes at least two water separation membrane units 1andwhich are provided in series in a flow direction of the target liquid. The water separation membrane uniton an upstream side out of the water separation membrane unitsandis connected to suction meansfor sucking a gas phase containing water through one condenser, and the one condensercondenses water in the gas phase and thereby separates the water. The gas phase sucked by the suction meansfrom the one condenseris transferred to at least one downstream condenserprovided downstream of the one condenser, and the downstream condensercondenses water in the gas phase and thereby separates the water. The water separation membrane uniton a downstream side of the water separation membrane unitis connected to a steam ejector, and the condenserfor condensing water in a gas phase passed through the steam ejectorcondenses water and thereby separates the water.
