Abstract
A gas sensor includes a metal shell, a gas sensor element held in the metal shell, a metal portion arranged between a flange portion of the gas sensor element and a seat portion of the metal shell and a porous thermal spray layer formed on the gas sensor element. When viewed in cross section along the direction of an axis of the gas sensor, a corner of the metal portion axially overlaps in position with or radially outwardly protrudes from an outer surface of a part of the thermal spray layer located on a side surface of the flange portion and is brought into contact with the seat portion. A rear end-facing surface of the metal portion is brought into contact with an outer surface of the thermal spray layer at a position radially inside the side surface of the flange portion.
