Abstract

In a method of manufacturing a magnet embedded core (), creation of unnecessary resin from the resin for fixedly securing the magnet is prevented. The method includes a resin charging step of charging resin material () in solid form into the magnet insertion hole; a melting step of melting the resin material () in the magnet insertion hole, and a pressurization step of pressurizing an interior of the magnet insertion hole (). The melting step includes melting the resin material () at least partly by preheating and inserting the magnet () into the magnet insertion hole ().
