Abstract
A method of manufacturing a rotor of a rotating electrical machine includes a method of manufacturing a rotor of a rotating electrical machine including a magnet and a rotor core forming storage space for storing the magnet. The rotor core forms an opening connected to the storage space. The method includes a first step of covering at least part of the opening with a first jig and a second jig having a non-adhesive resin film, a second step of putting an adhesive into the storage space, a third step of curing the adhesive in a state of being in contact with the non-adhesive resin film to form a plane surface facing an end ring of the rotating electrical machine, and a fourth step of separating the first jig and the second jig from the adhesive.
