<P>PROBLEM TO BE SOLVED: To provide a gas sensor having such a structure that the peripheral temperature of a thermally weak water repellent filter or elastic seal member is hard to become high. <P>SOLUTION: The gas sensor 1 has a housing 10, an insulator 12 on an element side, a gas sensor element 19, a cover 11 on a side of a gas to be measured, an insulator 13 on an atmospheric side and a cover 2 on the atmospheric side. The cover 2 on the atmospheric side has a caulked/fixed elastic seal member 17 on its base end side, introducing holes 210 and 220 for introducing the atmosphere into the cover 2 on the atmospheric side and the water repellent filter 23 covering these holes. A heat conduction inhibiting member 3 is arranged between the end surface 121 on the base end side of the insulator 12 on the element side and the end surface 131 on the leading end side of the insulator 13 on the atmospheric side. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
