Abstract:
A gas sensing element comprising a solid electrolytic body, a reference gas sided electrode provided on a surface of said solid electrolytic body so as to be exposed to a reference gas, and a measured gas side electrode provided on another surface of said solid electrolytic body so as to be exposed to a measured gas, whereina crystal face strength ratio of said measured gas side electrode according to X-ray diffraction satisfies the following relationship 0.7&lE;{I(200)/I(111)] or 0.6&lE;{I(220)/I(111)}where I(200) represents the intensity of an X-ray diffraction measurement for a crystal face (200) of said measured gas side electrode, I(111) represents the intensity of an X-ray diffraction measurement for a crystal face (111) of said measured gas side electrode and I(220) represents the intensity of an X-ray diffraction measurement for a crystal face (220) of said measured gas side electrode.
