Abstract:
This temperature sensor (1) is provided with: a pair of thermocouple wires (2); a temperature measurement contact point (3) at which the tips of the pair of thermocouple wires are joined; an outer tube (4) that accommodates the temperature measurement contact point (3) inside a tip part (401); an insulating material (5) that insulates the pair of thermocouple wires (2) and the outer tube (4); and a glass sealing material (6) that is filled in a base end part (402) of the outer tube (4). The temperature measurement contact point (3) is disposed in a gas phase (K) inside the tip part (401) of the outer tube (4). In an axial direction (X) along the center axis line of the outer tube (4), the shortest distance (L) from a base end (301) of the temperature measurement contact point (3) to a tip surface (501) of the insulating material (5) is in the range of 0-0.7 mm.
