摘要： A gas sensor (200) in which individual ones of connection terminals (30) have, at a rear end portion, a first connection portion (31) connected to a corresponding connector terminal (60). Individual ones of the connector terminals have, at an end portion on a side toward separator (40), a second connection portion (61) connected to the first connection portion. One of the first and second connection portions assumes the form of an insertion piece (61g), and the other assumes the form of a female portion (31g) into which the insertion piece is inserted. At least one of the insertion piece and the female portion has an elastic portion (31a). The insertion piece is fitted into the female portion, and the elastic portion thereby elastically bends, whereby the first and second connection portions are elastically connected.

摘要： A sensor includes a detector element, a connection terminal, and a separator. The contacting portion is in contact with a conductive member so as to overlap the conductive member in a thickness direction, which is a direction of thickness of the detector element between the principal surfaces. The separator includes an element accommodation space that accommodates a portion of an element contact portion and an element back portion, and a partition wall that separates the element accommodation space from a terminal accommodation space that accommodates the contacting portion and a portion of the conductive member and that is adjacent to the element accommodation space in the thickness direction. A frame main body is disposed in an element-side region, which is a region on an element-accommodation-space side in the thickness direction in a region obtained by extending the terminal accommodation space toward the front side in the axial direction.
