Abstract
Provided is a gas sensor in which a protective cover has no looseness even by repetitive use. The gas sensor includes a sensor element for detecting a predetermined measurement target gas component in a measurement gas; a protective cover which protects a side of one end portion of the sensor element; and a housing which houses the sensor element. The protective cover includes a brim portion at one end portion of an outer surface of the protective cover. The brim portion is brought into contact with a contact surface provided in said housing, and is held between a swaging portion and the contact surface, the swaging portion extending from the contact surface while bending, so that the protective cover is fixed to the housing. The brim portion is tilted at a tilt angle of 5° or more and 15° or less relative to a plane vertical to a central axis of the gas sensor.
