Abstract
There is provided a rotor core which increases the quality and reliability thereof by preventing the occurrence of a core separation of the rotor core. There is provided a rotor core including a plurality of substantially cylindrical core blocks which are stacked on each other; and a plurality of magnets, characterized in that a plurality of magnet holes extending in an axial direction are provided in the plurality of core blocks so as to extend over the plurality of core blocks in that the plurality of magnets are accommodated in each of the plurality of magnet accommodation holes and fixed therein with a resin, and in that an axial position of core block boundary planes where the plurality of core blocks are brought into abutment with each other and an axial position of magnet boundary planes where the plurality of magnets are brought into abutment with each other differ from each other.
