Abstract: PURPOSE:To obtain a small-sized and nondirectional hot-wire anemometer sensor having uniform characteristics by forming a hot wire in a fine spiral shape and by arranging it in the center of greater-pitch spiral power feeding lead and supporters. CONSTITUTION:A thin wire of a heating resistor such as a tungsten wire is formed spirally to obtain a hot wire 1, which is supported by supporters 2 and 3 serving as power feeding leads for the hot wire.
