Abstract

PURPOSE:To ensure the positioning and to prevent irregularities in performance, by fixing plate shaped fixing pieces to the upper ends of a plurality of electrode pins provided on a substrate, and fixing the gas detecting elements and a coil heater in parallel with the substrate. CONSTITUTION:A plurality of the electrode pins 2 are provided on the substrate 1 of a gas leakage warning device and the like. The plate shaped fixing pieces 6 are fixed to the upper end thereof. Electrodes 3a and 3a' of the gas detecting elements 3 and 3' and an electrode 4a of the coil shaped heater 4 are bonded to the fixing pieces 6 and supported in parallel with the substrate 1, under the state the elements 3 and 3' are inserted in the central part of the heater 4. Since the electrodes 3a, 3a' and 4a are overlapped on the fixing pieces 6 for a considerable length, misalignment of the position during the usage can be prevented owing to the reinforcing effect, centering of the elements 3 and 3' and the heater 4 can be readily performed, and the irregularities in the detecting performance can be eliminated.
