Abstract
An outlet of a sub passage that returns measured gas, which has passed through a flow sensor, from the sub passage to a main passage opens on an outer wall of a housing toward a downstream side in a reference direction. The outer wall of the housing includes a protrusion on the downstream side of the outlet. When the outlet and the protrusion are projected onto a projection plane perpendicular to the reference direction, the outlet and the protrusion partly overlap with each other on the projection plane. A relationship of θ1<θ2<90° is satisfied, where: θ1 is assumed to be an angle formed between a direction from an upstream end to a top, and the reference direction; and θ2 is assumed to be an angle formed between a direction from a downstream end to the top, and the reference direction.
