Abstract
A vacuum pump comprises: a cylindrical rotor; multiple heat insulating pins; and a stator having a cylindrical portion arranged with a predetermined gap in an outer peripheral side of the rotor and a fixing portion to be fixed to a pump base through the multiple heat insulating pins. The heat insulating pins have a lower thermal conductivity than those of the stator and the pump base, and support the fixing portion.
