ABSTRACT:
An oxygen sensor element for detecting an oxygen concentration, the oxygen sensor includes a solid electrolyte; a porous film covering the solid electrolyte at the gas-measuring side; and a reaction electrode provided on the porous film; wherein the porous film includes ceramic particles and metallic particles, and the metallic particles are bonded with the reaction electrode by a metallic bond. In this way, the porous film includes the ceramic particles and the metallic particles to form an irregular surface, and the reaction electrode is adhered to the irregular surface of the porous film in such a manner that the electrode bites into the surface of the porous film. The metallic particles in the irregular surface of the porous film are tightly bonded to the reaction electrode by the metallic bond.
