| PROBLEM TO BE SOLVED: To provide a vacuum pump with improved temperature determination accuracy, while suppressing increase in cost. SOLUTION: A nut 42 disposed on a shaft 3 of the vacuum pump has a magnetic body target 81 in which there is Curie temperature within a temperature monitoring range of a rotor 2. Difference in level is formed on a bottom surface of the nut 42 so as to constitute two fixing faces 42a, 42b, and the magnetic body target 81 is disposed on one fixing face 42a. A sensor output when a gap sensor is opposed to the magnetic body target 81 is divided by using difference in sensor output when the gap sensor is opposed to the fixing faces 42a, 42b, and using the divided value for the determination, the rotor temperature determination can be performed without being affected by a floating position of the shaft 3.
