Abstract
A gas sensor has a housing integrally formed with a caulked fixation portion. A detection element is inserted into the housing and fixed therein by caulking the caulked fixation portion via a sealing member such as a metallic ring. The caulked fixation portion is composed of a caulked portion and a buckling portion, and satisfies dimensional relationships of T,<T,<T,; 2<T,/T,, and 3<L/{(T,+T,)/2}. T,is a minimum thickness of the caulked portion, and T,is a maximum thickness of the caulked portion. T,is an average thickness of the buckling portion, and L is a length of the caulked portion in an axial direction of the gas sensor.
