Fluid Device

Abstract

A fluid device 10 that separates microparticles in a fluid using ultrasonic waves, the fluid device 10 includes an inflow flow path 20 through which the fluid flows; a separation flow path 30 into which the fluid flows from the inflow flow path 20; a first outflow flow path 40 that causes the fluid to flow out from the separation flow path 30; a second outflow flow path 50 that causes the fluid to flow out from the separation flow path 30; and an ultrasonic transmitter 60 that transmits the ultrasonic waves to the separation flow path 30 and at least one of the inflow flow path 20 and the first outflow flow path 40, and forms a standing wave along a first direction in each flow path to which the ultrasonic waves were transmitted.
