A flow rate control device 100 includes a control valve 6 provided in a flow path 1, a flow rate measurement unit 2, 3 for measuring fluid flow rate controlled by the control valve 6, and a controller 7. The controller 7 is configured so as to control the opening/closing operation of the control valve 6 to match the measurement integral flow rate based on the signal outputted from the flow rate measurement unit (Vn+Vd) to the target integral flow rate Vs.
