Abstract
A fluid device includes: a flow path through which a fluid flows; and an ultrasonic wave transmitter configured to transmit an ultrasonic wave to generate a standing wave to the fluid in the flow path along a first direction orthogonal to a flowing direction of the fluid. The ultrasonic wave transmitter is in contact with the fluid and faces an antinode region corresponding to any antinode in the standing wave.
