PROBLEM TO BE SOLVED: To provide a heat resisting mixing valve for high temperature gas inexpensive in manufacturing cost, excellent in heat resistance, corrosion resistance and durability and also excellent in controllability of a mixing flow rate of high temperature gas. SOLUTION: The heat resisting mixing valve for high temperature gas constitutes its characteristic feature of at least surfaces of a valve seat and a valve body making contact with high temperature gas being lined with a heat resisting material on the gas mixing valve made of a heated gas inflow port 10, a mixed gas outflow port 11 on the opposite side, a high temperature gas supply port 12 on one side in the cross direction, a valve body 1 on the opposite side of which a valve body drive device setting port 13 provided with a valve body drive device 4 is provided, the valve body drive device provided on the valve body drive device setting port, the valve seat 3 provided on a high temperature gas supply port end and the valve body 2 to be separated from and connected to the valve seat by the valve body drive device and to open and close the high temperature gas supply port.
