Abstract: A multi-nozzle device includes a nozzle body having a chamber into which fluid enters, a reference nozzle and a specific nozzle. The reference nozzle and the specific nozzle are each provided in the nozzle body. The inflow ends of the nozzles are communicated to the chamber. The outflow ends of the nozzles protrude from an end surface of the nozzle body. A length of the specific nozzle and a length of the reference nozzle differ from each other depending on the target discharge amount of the reference nozzle and the target discharge amount of the specific nozzle. An inner diameter of the specific nozzle and an inner diameters and of the reference nozzles and may be different from each other.
