PROBLEM TO BE SOLVED: To provide a steam attemper which has a simple mechanism and is inexpensive without using various kinds of sensors such as pressure sensors and flow rate sensors, control valves, and pumps for feeding coolant. SOLUTION: A vapor utilizing device 8 is connected with a steam pipe 1 in which an overheated steam flows. The first condensate reservoir 2 and the second condensate reservoir 3 are connected with the bottom of a jacket unit 35 of the vapor utilizing device 8. The reservoirs 2 and 3 are connected with a high-pressure liquid flow line 9. A connecting line 4 is connected with the bottoms of the each reservoir 2 and 3, and the upper edge of the connecting line 4 is connected with the inlet side of the mixing and separating device 7 of steam pipe 1. The overheated steam in the steam pipe 1 is cooled up to a predetermined temperature by a coolant fed to the steam pipe 1 from the first condensate reservoir 2 and the second condensate reservoir 3 through the connecting line 4.
