An air side cover (12) is attached to a proximal end of a housing (10) so as to confine an aerial atmosphere (142) therein. A measured gas side cover (13) is attached to a distal end of the housing (10) so as to confine a measured gas atmosphere (141) therein. A glass sealing material (25) airtightly seals a clearance between an inner surface (120) of an insulator (21) and an outer surface (150) of a sensing element (15). A contact interface (250) of the glass sealing material (25) protrudes toward a proximal end of the gas sensor (1) compared with at least an adjacent portion of the remainder of the glass sealing material (25). By melting and hardening a glass pellet (26), the sensing element (15) is airtightly fixed in the insulator (21). <IMAGE> |
