。[Claims for Utility Model Registration] 1. A flow rate measuring tube having a bypass passage is provided in a direction that crosses the mainstream passage at a nearly right angle, and the flow rate of air flowing through the mainstream passage is measured by a hot wire probe and a temperature probe provided in the bypass passage. A hot wire air flow meter characterized in that a bypass passage outlet provided in a flow measurement tube has a plurality of slit shapes. 2. The hot wire air flow meter according to claim 1, wherein the slit shape of the bypass passage inlet and outlet is such that the slit width becomes wider from the main passage pipe axis side toward the outer periphery. 3. The hot wire air flow meter according to claim 2, characterized in that the slit shape is triangular.
