Abstract
A fluid device includes: a flow path through which a fluid flows; a pressure chamber spaced apart from the flow path in a first direction (Y direction) orthogonal to a flowing direction of the fluid in the flow path; a communication path that is formed along the Y direction and that communicates the flow path with the pressure chamber; and an ultrasonic wave transmitter configured to transmit ultrasonic waves to the fluid in the pressure chamber to generate a standing wave along the Y direction in the flow path.
