Abstract
In a flow rate measuring device including a bypass channel having at least one bending portion and at least one channel portions, a detecting element is disposed in the bypass channel to detect the flow rate of measurement target fluid, a ratio L/H of a width H of the channel portion in which the detecting element is disposed, and a distance L from the bending portion at the upstream side of the detecting element to the upstream end portion of the detecting portion is set in range from 0 to 0.7, and a ratio D/H of a distance D from the wall surface of the base side of the detecting element to the center of the detecting portion of the surface of the detecting element and the width H of the channel portion is set in the range from 0.22 to 0.33.
