Abstract:
1. A sensor comprising: a sensor element including a detection portion formed at a front end portion adapted to face a measurement object, a rear end portion, a plurality of electrode terminals formed on a side surface of the rear end portion, and a chamfer provided on an edge defined by a rear end surface and the side surface having the electrode terminals formed thereon; a plurality of metallic terminal members elastically deformed and pressed against corresponding electrode terminals formed on the side surface of the sensor element so as to engage said sensor element; and an insulating retainer retaining therein said metallic terminal members and surrounding the rear end portion of the sensor element, wherein rear ends of the electrode terminals are spaced apart from a front end of the chamfer, and a flat surface of the sensor element is present between the rear ends of the electrode terminals and the front end of the chamfer, and wherein the distance between the rear ends of the electrode terminals and the front end of the chamfer as measured on the flat surface along the longitudinal direction of the sensor element is longer than the distance along the longitudinal direction between the front end of the chamfer and the rear end surface of the sensor element.
