摘要： In a gas sensor, not only a tube 70 covers lead wires 48, but also the tube 70 covers an outer peripheral surface of an end portion of an outer cylinder 46 including an open end 46a. A portion of the outer peripheral surface of the outer cylinder 46 covered with the tube 70 is gripped by a clamp 80. Thus, the clamp 80 integrally grips the tube 70 and the outer cylinder 46. Moreover, the tube 70 protrudes from the clamp 80 to a side of the outer cylinder 46 opposite from the open end 46a (protrusion amount L > 0). Further, the open end 46a of the outer cylinder 46 forms a large-diameter portion whose outer diameter is larger than an inner diameter D1 of the clamp 80.
