A measuring objective gas side electrode is provided on a surface of a solid electrolytic substrate. A reference electrode is provided on another surface of the solid electrolytic substrate. The measuring objective gas side electrode is exposed to a chamber. A gas introducing passage extends to connect the chamber to an external environment of the gas sensing element. A relationship S/Ld<=1.5 is established, where S represents a cross-sectional area of an inner open end of the gas introducing passage opening to the chamber, L represents a circumferential length of the inner open end, and d represents a thickness of the chamber in the vicinity of the inner open end of the gas introducing passage. |
