Abstract: A sensor includes a detection element; a plurality of terminal members, each of the terminal members including an elongated frame body portion extending along the axial direction, an element contact portion in elastic contact with an electrode terminal, and a folded portion connecting the frame body portion and the element contact portion; and a separator. The element contact portion of each of the terminal members has a turning portion which turns inward with respect to the width direction between the folded portion and a contact portion in contact with an electrode terminal. In those two of the terminal members which are adjacent to each other along the width direction, the distance along the width direction between the contact portions is smaller than the distance along the width direction between the frame body portions.

Abstract: A gas sensor is provided with a metal shell protecting member formed of a material superior in heat resistance to a metal shell, whereby a high-temperature measurement target (exhaust gas) is prevented from being in direct contact with a region, of a protector internal region of the metal shell, on the front side relative to a protector opposing surface. That is, in the gas sensor, it is possible to suppress corrosion, due to high temperature, of a region, of the protector internal region of the metal shell, on the front side relative to the protector opposing surface (an inner surface and a front end surface of a protector fixing portion), while the metal shell is formed of a material (SUS430) that can be subjected to working (crimping or the like) accompanied with deformation. Therefore, heat resistance of the entire sensor can be improved.
