PROBLEM TO BE SOLVED: To allow a covering body used as a battery component to be used as a vessel for activated carbon, and to form a wide gas channel in the activated carbon. SOLUTION: A sensor main body 4 employing a proton conductive film is arranged between a metallic washer 14 and the covering body 16 and held by a metallic can 24 through a dielectric gasket 22. Activated carbon is contained in the covering body 16, and atmosphere to be measured is introduced into the sensor main body 4 through apertures 17, 18, and water vapour and oxygen are fed through an aperture 15 of the washer 14. |
