Claim Text:
1. A microparticle sorting apparatus, comprising: a main channel through which a fluid including microparticles flows; a branch channel that is in communication with the main channel; a first actuator and a second actuator that cause a negative pressure to be generated in the branch channel, wherein the first actuator and the second actuator are arranged opposite to each other at a position corresponding to the branch channel, and a drive unit configured to apply different voltages to the first actuator and second actuator to cause a change in pressure in the branch channel, wherein the drive unit is configured to apply a voltage of a pulse waveform to one of the first actuator and the second actuator, while applying a voltage of a step waveform to other of the first actuator and the second actuator.
