<p>An exothermic resistor type air flow detector (1) which is compact and requires no special radiation structure. A control circuit comprised of a transistor (T) and a differential amplifier are formed with an exothermal resistor (Rh) on an insulated substrate (2), which is placed in an air passage (10) in which air current (Q) is to be measured. <IMAGE></p> |
