Abstract
A thermal-type air flow measuring device includes a heat generation heater and a sensor circuit. The heat generation heater is configured to heat a part of intake air drawn into an engine by heat generation upon energization of the heat generation heater. The sensor circuit is configured to at least control the energization of the heat generation heater and to make temperature of the heat generation heater higher than temperature of the heat generation heater at time of the measurement of the flow rate of air when an external signal is inputted into the sensor circuit from outside of the device.
