PROBLEM TO BE SOLVED: To provide a rotor for a permanent magnet synchronous motor, capable of reducing a lead time and being readily assembled. SOLUTION: The rotor for a permanent magnet synchronous motor is formed by integrally fixing a rotor core 11 comprising a plurality of laminated planar electromagnetic steel plates 11A in an axial direction, a permanent magnet 13 attached to a magnet through-hole 11a formed on the rotor core 11 and annular end rings 14 formed by die-casting and provided on both of the axial direction of the rotor core 11. In the rotor magnet, the permanent magnet 13 is inserted into the magnet through-hole 11a so as to have a gap 17 on both sides of the circumferential direction, the outside diameter of the end rings 14 is set to cover part of the permanent magnet 13 and a partitioning plate 15 for partitioning both sides of the axial direction from the center side in the gap 17.
