Abstract

An air flow measuring device takes in part of intake air flowing through an intake passage. The device includes a housing and a sensor. The housing defines a bypass flow passage through which taken-in intake air passes and which has an outlet that opens on an outer wall of the housing. The sensor is accommodated in the bypass passage to produce an electrical signal as a result of heat transfer between taken-in intake air and the sensor. The outlet of the bypass passage includes vertical and non-vertical openings. The vertical opening opens toward a downstream side of a flow of intake air in the intake passage and is provided perpendicular to the flow of intake air. The non-vertical opening is provided non-perpendicularly to the flow of intake air in the intake passage. The outlet is a continuous stretch of opening where the vertical and non-vertical openings are continuously formed.
