Claims

[Scope of Claim for Utility Model Registration] (1) A void is formed by removing the insulating material at the tip of a sheath in which a thermocouple wire is housed in the axial direction with an insulating material interposed therebetween, and a thermal contact is formed within the void. A sheathed thermocouple. (2) The sheath thermocouple according to claim 1, wherein a slit is carved at the tip of the sheath from which the insulating material has been removed. (3) A sheathed thermocouple in which a thermal junction is formed on the tip surface of a sheath that accommodates the thermocouple wire in the axial direction with an insulating material interposed between them.
