Abstract: An intake sensor includes a detection element, a heater, a housing, and a protector. The protector has two or more tubular portions spaced from one another in the radial direction. Of any two adjacent tubular portions, a second tubular portion on the outer side has tubular walls present in the penetration direction of first through holes of a first tubular portion on the inner side. Second through holes of the second tubular portion have an area equal to or greater than that of the first through hole. When the intake sensor is disposed in a model gas mixture of butane and air having air-fuel ratio of about 13, pressure of about 0.11 MPa, temperature of about 20° C., and flow rate of about 0 m/sec, and the heater heats the solid electrolyte member to the target temperature, no combustion flame is visually recognized on the outer surface of the protector.

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 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 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.
