    摘要: The present invention relates to an environmental condition sensor which is used to detect temperature etc., which sensor comprises an environmental condition sensor proper (1, 3,or 7), and a gas permeable structure (2 or 5) comprising .gamma.-MnO.sub.2, (Zn--Mn--FeO.sub.x) , and mAl.sub.2 O.sub.3.nCaO as the main composition thereof or an enamel layer (9) comprising .gamma.-MnO.sub.2, (Zn--Mn--FeOx), (.alpha.-Al.sub.2 O.sub.3.zeorite), and frit as the main composition thereof, which structure or layer surrounds the environmental condition sensor proper, so that carbon in oily smake and uncombustion gas striking the structure burns to prevent the oily smake and carbon from adhering to the environmental condition sensor proper (1, 3 or 7), whereby the degradation of the characteristics of the environmental condition sensor proper is avoided.
