Abstract: A gas sensor includes a gas sensor element that extends in an axial direction and that includes a detector, which detects a specific gas in a mixed gas; a metal shell that surrounds a periphery of the gas sensor element to hold the gas sensor element; a base that is disposed on a rear side of the metal shell and that covers a rear end portion of the gas sensor element, the base being made of a polymer material; and a metal tube that connects the metal shell and the base to each other and that includes a rear portion and a front portion, the rear portion being integrated with the base, the front portion forming an exposed portion that is exposed from the base. A part of the exposed portion of the tube is connected to the metal shell, and the base is disposed apart from the metal shell.

Abstract: 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.

Abstract: A sensor includes a detector element including a detecting portion and an element back portion on which two or more electrical connection terminal portions are formed; two or more connection terminals which each include an oblong frame main body that extends in an axial direction and an element contact portion that is electrically connected to a corresponding one of the electrical connection terminal portions; a separator that accommodates the connection terminals and the element back portion; and a base that surrounds an outer periphery of the separator. The separator includes a partition wall that is made of a resin material and partitions a plurality of accommodation spaces from each other. The accommodation spaces include an element accommodation space that accommodates portions of the element contact portions and the element back portion, and a plurality of terminal accommodation spaces which each accommodate one of the two or more frame main bodies.
