A simply configured thermal flowmeter can provide high measurement accuracy over a long period of time by suppressing the characteristics degradation due to adhering contaminants. On the surface of a diaphragm part, a heater resistor is formed. Temperature difference sensors through are disposed on the two sides of the heater resistor (upstream and downstream sides in the flow direction of an air stream). The temperature difference sensors are disposed upstream of the heater resistor while the temperature difference sensors are disposed downstream of the heater resistor. Outside the temperature difference sensors, heating temperature sensors are formed. Control is performed so that the temperature of the heating temperature sensors is set higher than the air stream temperature by a certain degree. Therefore, even if contaminants adhere to the sensor device, the temperature of the heating temperature sensors is held constant. Since the temperature difference sensors to detect the flow rate is located between the heating temperature sensors, the temperature change due to the contamination is small. This suppresses the characteristics degradation, making it possible to provide high measurement accuracy over a long period of time.
