An endoscope fluid controller of the present invention controls the opening/closing and flow rate of a duct. To control the flow rate of a water feed duct, air feed duct, and the like, for example, three pinch valves are disposed in series in a soft duct, and the pushing amount of a pressing portion of the pinch valve is adjusted so that the collapsing amount of soft duct changes. By controlling the opening/closing of the pinch valve by using a control switch disposed in the operation section, the flow rate in the duct can be controlled variably. In this case, three-stage control of flow rate can be carried out. In the case of a suction duct, the pinch valve can be disposed on the atmosphere open duct side. Also, a display section indicating the operation state and flow rate of each of various ducts is provided on a control panel etc. of an electromagnetic valve unit. On the soft duct other than the valve portion, a hard covering member for preventing duct deformation is disposed. Further, separately from the control switch in the operation section, a second control switch having the same function is disposed in an auxiliary peration section on the electromagnetic valve unit side.
