Abstract: A gas sensor includes a sensor element, a housing, a contact terminal, a second insulator, a lead wire, a sealing member, an inner periphery side cover and an outer periphery side cover. The inner periphery side cover is mounted on an outer periphery at a position on a base end side in an axial direction of the housing. The outer periphery side cover is disposed on the outer periphery side of the inner periphery side cover, forms a substantially cylindrical space with the inner periphery side cover and holds the sealing member on an inner periphery side.

Abstract: A gas sensor includes a sensor element, spring terminals, and a spring insulator. The spring terminals are formed of bendable wire. The spring insulator includes an insertion hole in which a proximal section of the sensor element is inserted and retaining grooves, which communicate with the insertion hole. The spring terminals each include a holding section retained in the associated retaining groove and an arm section, which extends from the holding section and comes into contact with the associated one of terminal contact portions of the sensor element while flexing with respect to the holding section. When viewed in an insertion direction of the sensor element to the insertion hole, a flexing direction of the arm section of each spring terminal with respect to the holding section is inclined with respect to the outer surface of the associated terminal contact portion.
