Abstract
A gas sensor includes a housing, an insulator, an inner cover, and an outer cover. An inner peripheral hole of the housing includes a rear end side hole and a front end side hole portion and a rear end side hole portion. A step portion which is formed in a slant shape is provided at a boundary between the front end side hole portion and the rear end side hole portion. The inner cover has a large-diameter portion which faces the step portion. The insulator has a flange which holds the large-diameter portion between itself and the step portion. A burr is formed on the surface of the large-diameter portion. The burr faces the surface of the step portion. This avoids inclination of the cover relative to the inner peripheral hole of the housing and obviates the risk of damage to or breakage of a device body.
