PROBLEM TO BE SOLVED: To provide a constant flow rate valve, which is reduced in size so that it can be set in a water supply facility with a large requested flow rate or a supply facility limited in setting space. SOLUTION: The constant flow rate valve includes a conically shaped coil spring that forms a valve element, a casing which forms a flow passage of fluid and stores the coil spring within the flow passage so that the minor diameter end side of the coil spring is turned to the upstream side, and a bypass which flows fluid separately from the fluid passing each space between windings of the coil spring.
