摘要： PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing gas sensor capable of positively fixing an atmosphere side cover to an aimed position of a housing and airtightly fixing an element side insulator and a sensor element to the housing. SOLUTION: A load is applied in the axial direction to insert the tip side of the atmosphere side cover 10 into the base end side of the housing 19. An overlapping portion of the housing 19 and the atmosphere side cover 10 is temporarily fixed in a state applied with the load. The housing 19 and the atmosphere side cover 10 are joined together by applying a final weld to the overlapping portion while rotating both the temporarily fixed housing 19 and atmosphere side cover 10 using the axial direction of the housing 19 as rotation axis.
