Further, a sheath having an inner diameter or an outer diameter approximately the same as the inner diameter of the heat-sensitive portion is provided continuously to the heat-sensitive portion, and an insulating material is filled inside the sheath and the heat-sensitive portion, and a thermocouple wire is provided. A metal sheath thermocouple for high-frequency induction heating, which is insulated by the above-mentioned insulating material, and is arranged such that a hot junction is located in a heat-sensitive part and the other end is led out from a sheath. (2) The metal sheath thermocouple for high-frequency induction heating according to claim 1, wherein a sheath having an outer diameter that is approximately the same or smaller than the outer diameter of the metal body is fixed to or integrally formed with the sheath. (3) The metal sheath thermocouple for high-frequency induction heating according to claim 1, wherein the bottomed sheath is inserted into the heat-sensitive portion of the metal body.
