<P>PROBLEM TO BE SOLVED: To provide a resin-sealing method for a rotor laminated iron core that economically manufactures the rotor laminated iron core with excellent workability, by eliminating a conventional process of removing a resin member and further eliminating a device used exclusively for removing the resin member. Ž<P>SOLUTION: The resin-sealing method for the rotor laminated iron core 20 is configured such that: permanent magnets 14 are inserted into magnet insertion parts 12 of an iron core body 13, formed by laminating a plurality of iron core pieces 10 and having the plurality of magnet insertion parts 12 around a central shaft-hole 11; subsequently, a resin member 18 is filled into each magnet insertion part 12, from each resin reservoir part 17 provided in either one die of an upper die 15; and a lower die 16 so as to fix each permanent magnet 14 while sandwiching the iron core body between the upper die and the lower die. A dummy plate 19 is formed with each resin injection hole 21, that makes each resin reservoir part 17 communicate with each magnet insertion part 12; the dummy plate is provided on the surface of the iron core body 13; the resin member 18 is cured after being injected the resin member into the magnet insertion parts 12 from the resin reservoir parts 17 via the resin injection holes 21 of the dummy plate 19; and then, the dummy plate 19 is removed from the iron core body 13.
