Abstract: 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.

Abstract: A method of manufacturing a gas sensor includes a step of preparing an assembly including a sensor element, a metal cylindrical body through which the sensor element penetrates in an axial direction, and a protection cover that is attached to the cylindrical body and that covers one end side of the sensor element. The method also includes steps of arranging a coil in a periphery of at least a portion of the cylindrical body at the same side as the other end of the sensor element with respect to the protection cover to avoid the protection cover of the assembly, induction heating the portion of the cylindrical body where the coil is arranged in the periphery by applying current to the coil, and hence removing oil adhering to the portion.

Abstract: In a holding portion of a contact fitting, in a state before crimping of core wires, the thickness of a first distal end portion and the thickness of a second distal end portion are both 70% or less of the thickness of the bottom portion. The thicknesses are both smaller than the diameter of core wires of a lead wire to be crimped. The first distal end portion and the second distal end portion are formed by compression processing. Using the holding portion, a first side portion and a second side portion are curved such that they face the bottom portion, and the plurality of core wires are surrounded and crimped with the bottom portion, the first side portion, and the second side portion.

Before the contact fitting is attached to the sensor element, a protrusion height of the conducting portion is 90% to 110% of a protrusion height of the supporting portion, and the protrusion heights and are relatively close to each other. The supporting portion and the conducting portion are elastically deformable and are curved in shape. The supporting portion and the conducting portion are arranged along a longitudinal direction of the contact fitting.

Abstract: In a main metal piece 60 and an inner cylinder 70 serving as cylindrical bodies before welding, a second end surface 75 is an inclined surface that inclines toward an end portion opposite from the second end surface 75 as the second end surface 75 extends toward the center axis, and an angle θ2a is 5° to 15°. Thus, the distance between a first end surface 65 and the second end surface 75 positioned in resistance welding increases toward the center axis, and an angle θc (=angle θ2a) between the first end surface 65 and the second end surface 75 is 5° to 15°.
