Provided is an oil diffusion pump equipped with an oil vapor generator capable of eliminating the problems occurring when a heater wire is used as a heating source for an operating oil. The present invention is a vacuum pump for which an oil vapor generator (70) is arranged within a casing (51) and this oil vapor generator is operated to vaporize an operating oil (8), thereby producing oil vapor and this oil vapor is sprayed from a jet (53, 53a) to exhaust intake air. The oil vapor generator (70) is equipped with: a container (71, 72) in the interior of which oil is stored, with the lower end of the tubular member (71), which comprises a material to be heated, being closed; and induction coil (75) wrapped around the atmosphere-side perimeter of the tubular member (71) (in particular, the case inner wall (71b)) with an insulating material (73) therebetween; and a power supply means that applies a low-frequency alternating current of several tens of Hz to several hundreds of Hz to the induction coil (75). The configuration is such that the tubular member (71) itself is heated when the power supply means is operated and the low-frequency alternating current is applied to the induction coil (75), thereby vaporizing the oil within the container.
