Abstract
A flow rate measuring device includes: a bypass passage; a flow rate detecting element; and a flow rate measuring circuit. The bypass passage includes: an inflow port; an outflow port; and a plurality of bent portions. The plurality of bent portions include first to third bent portions for forming U-shapes, and a fourth bent portion for bending the bypass passage bent at the third bent portion so as to be parallel to a mainstream flowing direction. The flow rate detecting element is arranged inside the bypass passage in a part after bending at the fourth bent portion. A route connecting the inflow port and the flow rate detecting element as a straight line is blocked by an inner wall surface of the bypass passage on an outer peripheral side, which is formed between the first bent portion and the second bent portion.
