<P>PROBLEM TO BE SOLVED: To provide a gas sensor having superior heat releasability, secured prescribed strength, and an superior shielding characteristics. <P>SOLUTION: This gas sensor is equipped with a sensor element 10 having a solid electrolyte body, and a case 60 enclosing the periphery of the sensor element 10 and having a mounting part 77 for external mounting. The overall case 60 is formed of an aluminum-based or copper-based metal material. The gas sensor is installed on a suction pipe 410 or on a cylinder head 405. The periphery of the sensor element 10 is enclosed by an external protector 742, an internal protector 743 and an external cylinder 744, and they may be formed of the aluminum-based or copper-based metal material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
