To provide a tip part mechanism of a temperature sensor capable of suppressing low a measurement error caused by an influence of the atmospheric temperature even when used for a measuring object having a large temperature difference with the atmospheric temperature, on which installation of a heat insulating material is not allowed, in measurement of a surface temperature of an apparatus such as piping or a vessel.
In this vacuum heat-insulating temperature sensor constituted of the temperature sensor and a box whose tip part is made of a metal, the temperature sensor is fitted on the box inside of the surface to be in contact with a measuring object of the box by welding or an adhesive, and an MI cable is used for a box penetration part of a lead wire of the temperature sensor, and the inside of the box is vacuum below 10 Torr.
