摘要： A gas sensor including coating layers (64) and (69) of fluorine or a fluorine compound formed on the surface of a separator (60), including a front separator (61) and a rear separator (66), disposed inside a sheath (30). The coating layers (64) and (69) have water impermeability and water repellency. Even in the case where moisture contained in the atmosphere within a sheath (30) forms dew on the surface of the separator (60), the coating layers (64) and (69) prevent soaking of moisture into the separator (60), to thereby secure the insulation property of the separator (60). Also, the coating layers (64) and (69) having water repellency prevent a water droplet from spreading on the surface of the separator (60) with resultant formation of a film of water, to thereby prevent flow of leakage current via a film of water.

摘要： [Objective] To provide a gas sensor in which the insulation among conduction members is stably secured through stable maintenance of the insulation property of a separator provided within a sheath, whereby a normal output can be obtained from a detection element.[Means for Solution] Coating layers 64 and 69 of fluorine or a fluorine compound are formed on the surface of a separator 60 (a front separator 61 and a rear separator 66) of an NOx sensor. The coating layers 64 and 69 have water impermeability and water repellency. Even in the case where moisture contained in the atmosphere within a sheath 30 forms dew on the surface of the separator 60, the coating layers 64 and 69 having water impermeability prevent soaking of moisture into the separator 60, to thereby secure the insulation property of the separator 60. Also, the coating layers 64 and 69 having water repellency prevent a water droplet from spreading on the surface of the separator 60 with resultant formation of a film of water, to thereby prevent flow of leakage current via a film of water.
