ンサ。 One end of the metal cylindrical inner cap is fitted and fixed to the base end outer periphery of the holder that holds the sensor element at its tip, and the large diameter end of the metal cylindrical outer cap is fitted to the other end of the metal inner cap. A lead wire lead-out member made of heat-resistant synthetic resin and having a through hole for leading out the lead wire is fitted to the inner periphery of the open end of the small diameter side end of the outer cap to form a lead wire lead-out portion from the sensor element section. Further, in the oxygen sensor, a sealing member is enclosed in an annular space surrounded by a tip bent part of the other end of the inner cap bent inwardly of the cap, a shoulder part of the outer cap, and a lead wire lead-out member, The flange portion of the lead wire lead-out member that contacts the annular space side of the bent end portion of the inner cap is extended to the vicinity of the outer cap, and the shape of the shoulder portion of the outer cap is changed as it goes outward. An oxygen sensor characterized in that the oxygen sensor is formed in a curved shape that is inclined so as to be close to the bent portion.
