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.
