Abstract
A metal terminal of a gas sensor includes a forward terminal member and a rear terminal member. The forward terminal member is made of a material superior in heat resistance to and greater in “0.2% yield strength” than a material of the rear terminal member. The forward terminal member has heat resistance suitable for a portion which comes into contact with a high-temperature detection element and is larger in an elastic deformation region than the rear terminal member, thereby providing good contact with the detection element and thus facilitating maintenance of electrical contact with the detection element. The rear terminal member is unlikely to have springback at a signal-wire connection portion to be connected to a lead wire, thereby facilitating maintenance of electrical connection with the lead wire.
