Abstract
An air flow meter has a housing, a flow rate sensor, and a physical-quantity measuring sensor. The housing therein defines a bypass passage into which a part of air flowing in a duct flows. The flow rate sensor is disposed in the bypass passage. The physical-quantity measuring sensor measures a physical quantity of air flowing in the duct and is disposed separately from the flow rate sensor. The housing has a recessed portion that is recessed from an inner wall surface of the bypass passage and that has a blind-passage shape. The physical-quantity measuring sensor is disposed in the recessed portion.
