<P>PROBLEM TO BE SOLVED: To provide a gas sensor easy in a disassembling work for classifying respective components at a low cost. <P>SOLUTION: This gas sensor 100 is provided with a gas detecting element 120 with an axial-directional tip side exposed to measured gas, and a cylindrical casing member 160 for surrounding the gas detecting element 120. The casing member 160 has an annular or annularly arranged brittle part 161h formed over along its circumferential direction. The brittle part 161h has strength at which the casing member 160 is broken in the brittle part 161h, when external force to rotate relatively each other reversely around an axis C is applied between a portion in an axial tip side of the brittle part 161h and a portion in an axial rear side of the brittle part 161h, out of the gas sensor 100. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
