PROBLEM TO BE SOLVED: To provide a temperature measuring device capable of simply and easily varying a utilizing temperature range with a simple constitution.
SOLUTION: On joint surfaces of flange members 10, 12 on the vacuum side and 12 on the atmospheric side, O-rings 131, 132 and 141, 142 are provided opposite to each other. The flanges 10, and 12 for vacuum side and atmospheric side are forcedly contacted by using screw members 16 while facing each O-rings of 131, 132 and 141, 142 respectively by crossing the O-rings with a middle part of a thermocouple 15 lead wires. The wiring of the thermocouple 15 between vacuum environment and atmospheric environment is performed by forcedly contacting the O-rings of 131, 132 and 141, 142 respectively, the vacuum sealing can be kept by elasticity of each O-rings, thereby the desired purpose is attained.
