サ。 The intermediate portion of the substrate, which has a sensor element portion for detecting oxygen concentration at the tip thereof, is fitted and held in a holder, and the inner periphery of a cylindrical case that is fitted and fixed to the outer periphery of the proximal end of the holder and the substrate By inserting the powder into the space surrounded by the outer periphery of the base end and press-fitting it in the direction of the holder via a spacer that is inserted into the cylindrical case through the substrate, the substrate is inserted into the cylindrical case. In the oxygen sensor configured to be clamped and fixed in the spacer via the powder, the substrate fits into the inner circumferential surface of the spacer through which it is inserted;
Further, by providing a positioning member integrally equipped with a plurality of pressing pieces that press the substrate in a direction away from the inner peripheral surface of the spacer by elastically deforming, and pressing the substrate with the pressing pieces of the positioning member. . An oxygen sensor characterized in that the spacer is positioned such that the substrate is disposed at a neutral position of the spacer.
