    Patent number: 11359995
    Abstract: A gas sensor (1) has a sensor element (21) extending in an axis direction and having, at a top end side thereof, a detecting portion (22) that detects gas; a stainless steel-made tubular metal shell (11) enclosing a radial direction periphery of the sensor element (21) and holding the sensor element (21) and having (a) a brim portion (14) protruding outwards in a radial direction and (b) a crimp portion (16) formed at a rear end side of the metal shell (11); and a sealing member (41) placed between the sensor element (21) and the metal shell (11). The crimp portion (16) is bent inwards in the radial direction and pressing down a rear end of the sealing member (41) toward the top end side. A Micro Vickers hardness of a cross section along the axis direction of the crimp portion (16) is 140 to 210 Hv.
