Claim 0:
1. A microparticle sorting device comprising:
a voltage supply unit that supplies a drive voltage to a vibration element that applies a vibration to an orifice that generates a fluid stream;
control circuitry configured to control a driving condition supplied to the vibration element on a basis of a relative relationship between a droplet discharged from the orifice and a satellite droplet present between droplets, using an absorption easiness indicating an easiness with which the satellite droplet is absorbed by either a preceding droplet or a subsequent droplet; and
a sorting unit that sorts the droplet containing microparticles on a basis of optical information detected from the microparticles flowing through a flow path, wherein the absorption easiness is calculated on a basis of a gravity center position of the satellite droplet and gravity center positions of the preceding and subsequent droplets.
