1. A sorting method, comprising:
deflecting, by generating a pressure, a target microparticle in a first fluid that flows from a main channel into a branch channel, wherein the branch channel is in communication with the main channel via a communication opening; and
introducing a second fluid from a discharge opening, wherein the discharge opening in the branch channel is at a downstream position of the communication opening.
