摘要： The present invention relates to improvement in the corrosion resistance of a weld joint between a metal shell and an outer casing. As a solution to this object, a metal shell 11 and an outer metal casing 16 are laser welded to each other via a weld joint 100 by irradiating a laser beam onto the entire circumference of a crimped area 90 in a circumferential direction of the outer metal casing 16. This laser welding operation is performed at a plurality of positions (two positions) displaced from each other in the direction of an axis O so that the weld joint 100 is formed with a front weld zone 110 and a rear weld zone 120.

摘要： A gas sensor suppresses the deterioration of gas tightness caused by failure of a sealing material. The gas sensor includes: a housing; a sensor element arranged inside the housing; a sealing material filling a gap between the sensor element and the housing; an insulation member arranged on a proximal end side of the sealing material; and an annular metal ring arranged on a proximal end side of the insulation member. The sealing material, the insulation member and the metal ring are fixed under pressure by caulking from a proximal end side to a distal. A proximal-end facing surface of an inner peripheral portion of the metal ring is spaced apart from the caulking portion in an opposing region where an inner end of the caulking portion and the metal ring face each other in an opposed manner.
