    • PROBLEM TO BE SOLVED: To provide a sorting device capable of high-speed analysis and sorting with safety, high speed, and low cost, by precluding cross-contamination between samples, contamination of samples, biohazard to the users, an expensive flow cell and an expensive orifice part, and fine adjustment work for the flow cell and the orifice. SOLUTION: The device (A) for sorting particles is provided with a microchip 1 in which a flow channel 11 through which liquid contanning particles is flown and an orifice 12 for discharging the liquid flowing through the flow channel 11 to a space outside the chip are provided, a vibratory element 2 for making and ejecting a droplet of the liquid at the orifice 12, a charging means for giving charge to the ejected droplet D, an optical detecting means 3 for detecting an optical characteristic of the particles flowing through the flow channel 11, paired electrodes 4, 4 arranged along the direction of movement of the ejected droplet D and opposed with the moving droplet D therebetween, and two or more vessels for collecting the droplet D passing between the paired electrodes 4, 4.
