ABSTRACT:
An oxygen sensor including an oxygen sensing element having one closed end and inner and outer electrode layers formed on the inner and outer surfaces thereof, an output withdrawing lead wire electrically connected to the inner electrode layer formed on the inner surface of the oxygen sensing element, and a metallic terminal disposed in connection between the output withdrawing lead wire and the inner electrode layer. The metallic terminal includes opposed resilient portions separated by a gap and disposed in contact with the inner periphery of the inner electrode layer to apply a radial force to the inner electrode layer, whereby not only the damage of the oxygen sensing element is prevented but also the mounting operation can be done easily without threaded insertion of the metallic terminal.
