Abstract
A method of manufacturing a rotor that includes a rotor core and a permanent magnet fixed to the rotor core using an adhesive, the method includes applying the adhesive, which contains a volatile agent, to an adhesive placement position of the permanent magnet; drying the adhesive by volatilizing the volatile agent by a magnet heater directly heating the permanent magnet such that a temperature of the permanent magnet becomes higher than a temperature of the adhesive after applying the adhesive; placing the permanent magnet on the rotor core after drying the adhesive; and fixing the permanent magnet to the rotor core by curing the adhesive after placing the permanent magnet.
