To provide a substance mixing apparatus that is capable of uniformly mixing a certain amount of trace substances and also mixing minute particles.;[Solving Means] Provided is a substance mixing apparatus including: two or more flow paths (11, 12, 13) in which orifices (111, 121, 131), from which a fluid that flows therethrough is externally discharged, are formed; oscillation devices (112, 122, 132) that form droplets of the fluid discharged from each of the orifices (111, 121, 131) by oscillating at least the orifice (111, 121, 131) part of the flow paths at a predetermined oscillation frequency and discharge the droplets; and means for causing the droplets (A, B, C) discharged from the orifices (111, 121, 131) of the flow paths (11, 12, 13) to collide with one another.
