Abstract
A gas sensor comprises an atmosphere-side cover, ventilation filter, and filter cover as well as a sensing element and housing. The atmosphere-side cover has i) a first section of a first diameter located on a tip-end side in a axial direction of the housing and fixed on an axially base end of the housing, ii) a second section of a second diameter smaller than the first diameter, the second section being located on an axially base-end side, iii) a stepped section formed between the first and second sections, and iv) a rib protruding outward from the second section and being formed between the stepped section and the second section. The ventilation filter is mounted on the second section and has an axially tip-end section being in contact with an axially base-end section of the rib. The filter cover fixes the ventilation filter between the second section and the filter cover.
