    摘要: A pad-equipped thermocouple includes a sheathed thermocouple in which a pair of thermocouple elements and an inorganic insulating powder for holding the thermocouple elements are accommodated in a sheath. An opening of the sheath is sealed by a sealing member. A pad is welded to a pipe and configured to hold the sheathed thermocouple to a surface of the pipe. A temperature measuring junction formed by the pair of thermocouple elements is exposed to a side face of the sheath in a leading end portion. The pad includes an accommodation portion accommodating the leading end portion such that the leading end portion can be inserted into and pulled out from the accommodation portion along the surface of the pipe, and the accommodation portion accommodates the leading end portion in a state where the temperature measuring junction and the surface of the pipe are in contact with each other.
