Abstract:
A gas sensor is equipped with a sensor element which detects a specific gas concentration within a gas that is being measured, a housing having the sensor element disposed in the interior thereof and retained therein, and an element cover disposed at an axial-direction tip end of the housing. The tip of the sensor element is provided with a gas introduction part. The element cover has an inner cover and an outer cover, with a space opened between the inner cover and outer cover. Inner side flow holes provided in the inner cover are disposed closer to an axial-direction base end than is a tapered-diameter step part. The distance between the tip of the sensor element and the inner-side flow holes of the inner cover, with respect to an axial direction, is less than or equal to 1.6 mm.

Claim (Index 5):
The gas sensor according to  claim 1 , wherein the sensor element comprises:\n a measurement gas chamber into which the gas that is being measured is introduced from the gas introduced part; a reference gas chamber into which a reference gas is introduced; a solid electrolyte body with oxygen ion conductivity, disposed between the measurement gas chamber and the reference gas chamber, having a first main face that faces the measurement gas chamber and a second main face that faces the reference gas chamber; a reference electrode that is formed on the second main face of the solid electrolyte body; a pump electrode that is formed on the first main face of the solid electrolyte body and which, together with the reference electrode and a part of the solid electrolyte body, constitutes a pump cell that adjusts the oxygen concentration within the gas that is being measured; a sensor electrode that is formed on the first main face of the solid electrolyte body and which, together with the reference electrode and a part of the solid electrolyte body, constitutes a sensor cell that outputs a signal in accordance with the specific gas concentration in the gas that is being measured, after adjustment of the oxygen concentration by the pump cell; and a heater for heating the solid electrolyte body, disposed opposite the solid electrolyte body, with the solid electrolyte body separated from the heater by the reference gas chamber, wherein: the pump electrode is formed closer to the axial-direction tip end of the sensor element than is the sensor electrode; and the base position of the inner-side flow holes is disposed closer to the axial-direction tip end than is a tip position of the pump electrode, with respect to an axial direction of the gas sensor.
