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 1):
A gas sensor comprising:\n a sensor element which detects a specific gas component concentration in 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; with a gas introduction part being provided at a tip of the sensor element, for introducing the gas that is being measured into the interior of the sensor element; and with the element cover having an inner cover formed in a tubular shape having a bottom, disposed to cover the axial-direction tip end of the sensor element, and having an outer cover formed in a tubular shape having a bottom, disposed to form a space that is open to an outer side of the inner cover, wherein: a side of the inner cover is provided with inner-side flow holes for circulating the gas that is being measured, and an inner bottom flow hole is provided in the bottom of the inner cover, for circulating the gas that is being measured; the inner cover is provided with a tapered-diameter step part that is tapered inwards toward the axial-direction tip end and the inner-side flow holes are disposed closer to an axial-direction base end than is the tapered-diameter step part; outer-side flow holes are provided in the side of the outer cover, for circulating the gas that is being measured; a tip position of the outer-side flow holes is disposed closer to the axial-direction tip end than is the bottom of the inner cover; and a distance between the tip of the sensor element and a base position of the inner-side flow holes, with respect to an axial direction, is less than or equal to 1.6 mm.
