Abstract

PURPOSE:To improve the durability of the element and to heat the element uniformly, by coating a metal oxide semiconductor with a material having gas permeability, and providing a heating coil on the outside of the coating. CONSTITUTION:A gas response body 7 comprising the metal oxide semiconductor made of SnO2 and the like is coated by the gas permeable mateial 8. As the gas permeable material 8, aluminum, clay, chamotte, asbestos, glass wool, and the like can be used. The coil heater 13 made of base metal such as Nichrome wire and Kantal wire is arranged on the outside of the element 2 with a space being mainteined from the element. In this constitution, the element is uniformly heated, sensitivitly is improved, and contamination is not caused by dust and the like.
