In a method for manufacturing a rotor, each of adhesive placement portions that are provided between a surface of a permanent magnet on the radially inner side and grooves is formed so as to cover a part of an adhesive applied to the permanent magnet on the radially inner side and parts of the adhesive on both sides in the circumferential direction.

Method for manufacturing a rotor

A method of manufacturing a rotor includes: applying the adhesive to an adhesive placement position on an outer peripheral surface of the permanent magnet or an inner peripheral surface of the magnet hole, the adhesive containing an expansive agent that is expanded by being heated to a temperature that is equal to or higher than an expansion temperature; drying the adhesive after applying the adhesive; inserting the permanent magnet into the magnet hole of the rotor core after drying the adhesive; and fixing the permanent magnet and the rotor core to each other using the adhesive by expanding the expansive agent and curing the adhesive by heating the adhesive to a temperature that is equal to or higher than the expansion temperature after inserting the permanent magnet.
