摘要： A gas sensor including: a gas detection element; a metal shell extending in an axial direction; and a metal cylinder extending in an axial direction, wherein a leading end portion of the metal cylinder surrounds a base end portion of the metal shell and is fixed to the metal shell via a circumferential welded portion. The metal shell includes: Fe in an amount equal to or more than 50.0 mass %; C in an amount of 0.02 mass % to 0.15 mass %; Cr in an amount of 11.5 mass % to 18.0 mass %; and Nb in an amount equal to or more than twice amount of C in mass %.
