Abstract
A gas-flow measuring apparatus including a semiconductor chip and a sensing circuit. The semiconductor chip includes an electric heater and two temperature-detecting elements. One of the temperature-detecting elements is located closer to the heater than the other. The sensing circuit generates voltage in response to the flow rate of gas flowing through a gas passage.
