Abstract: A temperature sensor includes: a sheath tube; a pair of thermocouple wires inserted into the sheath tube; a temperature measuring junction of the pair of thermocouple wires; an insulating support disposed in the sheath tube; and a tip protective tube covering the outer periphery of a tip end of the sheath tube to surround the temperature measuring junction. The tip protective tube includes a base-end side tube portion and a tip-end side tube portion, the tip-end side tube portion having a diameter smaller than that of the base-end side tube portion. The tip-end side tube portion has a tip-end side portion filled with a first insulating filler in which the temperature measuring junction is buried. In the remaining part on the inside of the tip-end side tube portion, an air layer is formed.

Abstract: A temperature sensor includes a metal tube containing thermo-sensitive element and filled with an insulating filling material, and a housing to which the metal tube is fixed. The metal tube includes a small-diameter part and a large-diameter part. The distal end of the small-diameter part is located beyond a virtual line. The virtual line passes a center of a maximum virtual circle which is an inscribed circle that contacts at least three inner surfaces of the pipe in a cross-section perpendicular to an axial direction of the pipe, and is perpendicular to a center axis line of the metal tube. The whole of the small-diameter part and the part of the large-diameter part filled with the filling material are located within a center virtual circle which is coaxial with the maximum virtual circle and has an inner diameter of ⅔ of that of the maximum virtual circle.

Abstract: A temperature sensor includes a temperature detector having a thermosensitive element, element electrode wires, leads, and intermediate members. The temperature sensor is formed such that ends of the element electrode wires are embedded in the temperature detector, the leads are electrically connected to the respective element electrode wires, and the intermediate members electrically connect the element electrode wires to the respective leads. Each element electrode wire and the corresponding intermediate member are arranged being aligned in the extending direction, and bonded to each other, with opposing surfaces facing each other being abutted each other. The intermediate member and the corresponding lead are juxtaposed in a direction perpendicular to the extending direction, and bonded being overlapped with each other.
