Abstract
An outer tube and a rubber plug are swaged at two sites, a first swaged section located on the side of connections between contact fittings of a connector and leads and a swaged section located closer to an open end of the outer tube than the first swaged section, such that the inside diameter of a portion of the outer tube is greater than the inside diameter. This prevents reduction of the detection accuracy of a gas sensor because sealing properties can be enhanced by heavily swaging at the second swaged section than the first swaged section. Additionally, excessive force can be prevented on the connections and the leads by lightly swaging the first swaged section rather than the second swaged section. Thus, the disconnection between the connector and the leads can be prevented.
