Zusammenfassung:A rotor, a motor, an air-conditioning apparatus, and a method for manufacturing a rotor are provided with high productivity and reliability and with structural stability. The rotor includes a shaft, an inner core into which the shaft is inserted, an outer core provided on a radially outer side of the inner core and composed of a plurality of divided cores formed by stacking a plurality of thin plate materials and connected in an annular shape, and a coupling member made of resin, coupling the inner core and the outer core together, and covering both end faces of the outer core in an axial direction of the shaft. The outer core has radially outer parts of the divided cores brought into close contact with each other.
