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.
