Abstract
A heat-sensitive flow rate sensor in which a fluid shield is provided so as to cover at least part of a flow velocity probe disposed in a detecting tube, thereby preventing part of heat-sensitive resistor from being directly subjected to change in the flow velocity of a fluid. Temperature of the heat-sensitive resistor is maintained substantially constant even when the fluid flow rate has been drastically changed, thus providing good response characteristic of the flow rate sensor.
