装置。 A hot film element having a metal coating applied to the surface of a cylindrical body and having leads protruding from both ends is connected to a pair of terminals set upright at the opening of a plug installed in the intake passage of an engine. The air flow rate is measured by connecting and attaching the hot film element and controlling the current supplied to a bridge circuit formed by the hot film element and the resistor as the resistance value changes in accordance with the air flow rate of the hot film element. A dust adhesion prevention device for a hot film flow meter, characterized in that a dust adhesion prevention member is provided upright on the plug to cover the pair of leads and terminals close to the upstream side of the intake passage.
