PURPOSE: To uniformly mix a plurality of solutions in a predetermined ratio, by mixing solutions while pulverizing the same by the vibration of a piezoelectric element.
CONSTITUTION: Solutions flowing out from solution supply sources are pulverized by a solution pulverizing apparatus 1 and mixed at a confluent point 6. In the solution pulverizing apparatus 1, a piezoelectric element 7 vibrates by applying a control signal between the piezoelectric element 7 and a vibration plate 8 and this vibration is transmitted to the solutions in a solution housing 10 and the solutions are discharged in a particulate form from a discharge port 11. The number of discharged particles per a unit time coincide with the frequency of the control signal and, by changing said frequency, a mixing ratio flow amount can be easily mixed. Even when solutions having high viscosity are mixed, particles of other solution can enter between particles and uniform mixing is enabled without using a mixing apparatus.
