Abstract
A protection tube thermocouple (5) includes a thermocouple (52), and a protection tube (51) which accommodates the thermocouple (52). The protection tube (51) includes a conical portion (511) formed on a front end (54) side of the protection tube (51); and a hollow portion (53) which extends in the length direction of the protection tube (51) for connecting between a front end (54) and a rear end (55) of the protection tube (51) in the inside of the protection tube (51), and into which the thermocouple (52) is received. The hollow portion (53) in the conical portion (511) has a tapered portion (532) configured such that the sectional area of the hollow portion (53) decreases toward the front end (54).
