A thermal type of flow rate sensor includes heat-generating and temperature-compensating resistors RH and RC which are located within a fluid passage to measure the flow rate of the fluid. The linear term coefficient, alpha , of the temperature coefficient of resistance of RC is made smaller than that of RH, whereby any temperature-compensating electric circuit and circuit control can all be dispensed with and the flow rate of a fluid can be precisely detected over a wide temperature range.
