<p>A gas sensing element (1) comprises a solid electrolytic element (10), a measured gas sensing electrode (12) provided on an outer surface of the solid electrolytic element (10), and a reference gas sensing electrode (11) facing a reference gas chamber (100). A heater (3) is accommodated in the reference gas chamber (100). A contact portion (30) is provided on an outer cylindrical surface of the heater (3) so that the contact portion (30) is brought into contact with an inside surface of the solid electrolytic element defining the reference gas chamber (100). A heating peak position of the heater (3) is in the vicinity of the contact portion (30). <IMAGE></p> |
