An object is to provide a gas sensor which can suppress positional shift of a to-be-held member such as a gas detection element, as well as a method of manufacturing the gas sensor. A gas sensor ( 101 ) includes a gas detection element ( 111 ), a metallic shell ( 131 ), a plate packing ( 157 ), and a first packing ( 159 ). A proximal end surface ( 113 t 2 ) of a projection ( 113 ) of the gas sensor element ( 111 ) and a central inner circumferential surface ( 135 n) of the metallic shell ( 131 ) form an acute-angle clearance ( 120 ). The first packing ( 159 ), which has a wedge-like cross section, is disposed in the clearance ( 120 ) such that the first packing ( 159 ) is pressed against the proximal end surface ( 113 t 2 ) of the projection ( 113 ) of the gas sensor element ( 111 ) and the central inner circumferential surface ( 135 n) of the metallic shell ( 131 ). |
