Abstract
A thermal flow detecting apparatus detects fluid flow in a main flow passage. A bypass passage portion is provided through which some fluid bypasses the main flow passage. A detecting element is provided in the bypass passage portion and arranged at a location eccentrically displaced from the center of a cross section of the bypass passage portion. A throttle portion is provided upstream of the eccentric detecting element in the bypass passage portion for throttling the cross section partially on a side of the detecting element.
