(54) Fluid mixer and method for forming mixed fluid


(57) A fluid mixer includes: first-fluid introduction paths (11) into which a first fluid is introduced; second-fluid introduction paths (12) which are arranged alternately with the first-fluid introduction paths, and into which a second fluid is introduced; first bifurcation paths (13) formed of ends of the first-fluid introduction paths and ends of the second-fluid introduction paths, the ends bifurcating in two directions; first confluence paths (14) formed by combining ends of the first bifurcation paths with adjacent ends of different first bifurcation paths; n bifurcation paths (19) formed of ends of n-1 confluence paths (18), the ends bifurcating in two directions; n confluence paths (20) formed by combining ends of the n bifurcation paths with adjacent ends of different n bifurcation paths; and mixed-fluid discharging paths (21) formed of the n confluence paths extended to the end, the mixed-fluid discharging path for discharging a mixed fluid.
