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