PROBLEM TO BE SOLVED: To provide a fluid mixer for preventing productivity and maintainability from decreasing and improving operability and reliability even if no precise pressure control is used. SOLUTION: The fluid mixer 10 includes channel selection mechanisms 6a, 6b in mixing tank channels 3a, 3b. As the pressure of liquid 1a is increased gradually, the channel selection mechanism 6a limits the channel to a branch channel 3a at a prescribed pressure or lower, feeds the liquid 1a to a valve 5b, and closes down the mixing tank channel 3b. When the liquid 1a exceeds a prescribed pressure, the channel selection mechanism 6a also permits a channel to a mixing tank 9 and feeds a liquid to the mixing tank 9. The mixing tank channel 3b has been closed down by the valve 5b, thus preventing the liquid from being fed from the mixing tank 9 to a supply tank 2a. Similarly, liquid 1b also does not flow into the supply tank 2a and is fed to the mixing tank 9. In the fluid mixer 10, it is not necessary to operate the valves from the outside, thus preventing a flow from the mixing tank to the supply tank even if the pressure and flow rate of the liquid are not controlled strictly.
