PROBLEM TO BE SOLVED: To provide a sensor unit for thermal analysis equipment, capable of keeping a heat conduction between a furnace body and samples to detect a temperature difference between the samples with high sensitivity, while suppressing the heat conduction between a measurement sample and a reference sample, and to provide a method for manufacturing the same. SOLUTION: The sensor unit 30 for the thermal analysis equipment 1, which detects the temperature difference between the measurement sample S and the reference sample R in each sample container, includes: a base part 31 formed of an insulator and installed in the vicinity of a temperature-controlled furnace unit; a multiple thermocouple 32 formed by joining two kinds of thermocouple elements alternately, wherein a particular part of the thermocouple element is joined to the base part; and a pair of heat sensitive parts 35, 36 formed of an insulator, having a mounting surface on which each sample container is mounted, and joining to element junctions of the multiple thermocouple. The pair of heat sensitive parts 35, 36 are installed spaced apart from the base part 31. COPYRIGHT: (C)2008,JPO&INPIT
