PROBLEM TO BE SOLVED: To provide a rotor laminated core excellent in productivity, shape accuracy, and rotation efficiency; and to provide its manufacturing method. SOLUTION: The rotor laminated core has a basic block core 17 which has a basic laminate 14 which is made by the lamination of core pieces 11 and is equipped with a shaft hole 12 at the center and a plurality of magnet insertion holes 13 around the shaft hole 12, permanent magnets 15 which are inserted into each of the magnet insertion holes 13 of the basic laminate 14 and are shorter than the depth of the magnet insertion holes 13, and resin members 16 which are filled on and around the permanent magnets 15 inserted into the magnet insertion holes 13 so as to integrate the basic laminates 14 and the permanent magnets 15. A plurality of basic blocks 17 are stacked, while substantially according the axes of the shaft holes 12 with one another, and the fellow basic block cores 17 are integrated with one another by coupling 27.
