PROBLEM TO BE SOLVED: To provide an inexpensive waste steam recovery device capable of surely and instantaneously sucking waste steam generated in large amounts. SOLUTION: A vacuum tank 2 is connected with a waste steam passage 1 through a valve 8. A suction means 4 is connected with a lower part of the vacuum tank 2. The suction means 4 is constituted by successively connecting an ejector 11, a liquid tank 13 and a circulation pump 14. A cooling water branch pipe 6 is connected with a right upper part of the vacuum tank 2. A large amount of waste steam generated at a lower part of a waste steam collecting port 3 is surely sucked into the vacuum tank 2 kept in a prescribed vacuum pressure state, by fully opening the valve 8 of the waste steam passage 1.
