<P>PROBLEM TO BE SOLVED: To provide a gas sensor in which electric connection between an outside terminal and a gas sensor element is hardly cut. <P>SOLUTION: A gas sensor 100 comprises: a gas sensor element 3 including a bottomed cylindrical element body 3s whose tip is exposed to gas to be measured and outside electrodes 3c provided on an outside surface from the tip of the element body to a rear end thereof; an outside terminal 91 including a cylindrical part 93 that encloses, at a tip thereof, the rear end of the gas sensor element from a radial direction and is electrically connected to the outside electrodes forms a cross section C shape formed with a slit M extending from a tip edge to a rear end edge in an axis line O direction and extends a diameter by elastic force when externally fitted to the rear end of the gas sensor element; and a separator 111 whose tip-facing surface 111S is in contact with a rear end surface of the cylindrical part and for externally fitting a tip of the cylindrical part into the rear end of the gas sensor. The rear end of the cylindrical part is provided with a first notch 93a connected to the rear end edge 93e and notched in the axis line direction toward the tip side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
