Abstract
Provided is a gas sensor in which a connection terminal can be favorably fitted onto a cylindrical sensor element without causing a breakage of the connection terminal. An oxygen sensor (1) includes an outer connection terminal (29) having an outer fitting portion (53), an extension portion (55) extending inwardly from an axially intermediate point of the outer fitting portion (53) and pulling prevention portions (75) and (77) formed on rear end parts of the outer fitting portion (53) at positions adjacent to the extension portion (55). When the extension portion (55) of the outer connection terminal (29) is inserted in and pulled out from a through hole (23) of a separator (27), the extension portion (55) can be prevented from further pulling in the through hole (23) by contact of the pulling prevention portions (75) and (77) with a front end surface of the separator (27).
