In the case of a laminated rotor core, insertion of permanent magnetsand filling of resininto each of magnet insertion holesare performed in order to cancel out a problem of an imbalanced weight estimated from a deviation of lamination thickness in a circumferential direction of a laminated core body, and a manufacturing method includes a step of measuring a deviation of lamination thickness in which an imbalanced weight is estimated by measuring the deviation of lamination thickness in the circumferential direction of the laminated core body, and a step of balance adjustment in which the insertion of the permanent magnetsinto each of the magnet insertion holesand the filling of resininto each of the magnet insertion holesare performed in a manner that cancels out a problem of this imbalanced weight.
