摘要： PROBLEM TO BE SOLVED: To provide an air-flow rate measuring device which minimizes the influence of matters attaching onto an exothermic resistor or the like, during stoppage of an engine so as to improve the measurement accuracy. SOLUTION: A flow rate of air sucked into the internal combustion engine is detected by using the exothermic resistor 1. After the internal combustion engine is stopped, a power management circuit 4 keeps the temperature of the exothermic resistor 1, at a level equal to or higher than the same during driving the internal combustion engine, until the temperatures of devices mounted on the internal combustion engine and an intake air system thereof become equal to or lower than the temperature, at which a volatile gas, such as oil vapor, is generated. The power management circuit 4 detects the air temperature by a heat-sensitive resistor 2 for detecting the temperature of the air sucked into the internal combustion engine. Based on the detected temperature, the power management circuit also keeps the temperature of the exothermic resistor at a level equal to or higher than the same during driving the internal combustion engine, after the stoppage of the internal combustion engine.
