A vacuum pump comprising:
- a pump housing;
- a motor configured to rotate in the pump housing;
- a rotor configured to be rotatably driven by the motor;
- a stator provided between the rotor and the pump housing;
- and
- a heat insulating member provided between the stator and the pump housing,
- wherein the heat insulating member has a cylindrical main body including an upper contact surface provided at an upper portion of an inner peripheral surface of the cylindrical main body and a lower contact surface provided at a lower portion of an outer peripheral surface of the cylindrical main body,
- the upper contact surface is subjected to mechanical processing and contacts a side surface of the stator,
- the lower contact surface is subjected to mechanical processing and contacts a side surface of the pump housing,
- the heat insulating member has a processing gripping target portion gripped with a processing jig when the upper contact surface and the lower contact surface are mechanically processed, and
- the processing gripping target portion is provided on at least one of the inner and the outer peripheral surfaces of the main body and between the upper contact surface and the lower contact surface in an axial direction of the cylindrical main body.
