Abstract
An air flow rate measurement device capable of suppressing disturbance of a flow of measured gas and reducing a characteristic influence due to water droplets flowing with intake air is realized. An edgeof the upstream side where air flows in a circuit boardon which a flow rate detection portionis mounted is provided with a segmentation portionto be a semicircular notch structure to segment the edge. Water droplets flowing with measured gascan be captured by the segmentation portionto inhibit the water droplets from arriving at the flow rate detection portion
