Claim 7:
8. A microparticle sorting method executed by a microparticle sorting device, the method comprising:
supplying a drive voltage to a vibration element that applies a vibration to an orifice that generates a fluid stream;
sorting a droplet containing microparticles on a basis of optical information detected from the microparticles flowing through a flow path; and
controlling a driving condition supplied to the vibration element that applies the vibration to the orifice on a basis of a relative relationship between the droplet discharged from the orifice that generates the fluid stream 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, 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.
