A flow controller for controlling a flow rate of a fluid flowing through a fluid passage comprises a control valve for which a degree of opening of a valve is adjusted by a control signal, an orifice arranged on an outflow side of the control valve, a combined sensor arranged on an inflow side of the orifice for almost simultaneously detecting a pressure and a temperature of the fluid, and a control circuit. The combined sensor includes a pressure-detecting element for deriving a detection signal corresponding to the pressure of the fluid, and a temperature-detecting element for deriving a detection signal corresponding to the temperature of the fluid. The pressure-detecting element and the temperature-detecting element are arranged closely to one another on an identical surface of a pressure-receiving section.
