ABSTRACT:
A production method for a rotor for a permanent magnet-type rotary electric machine, includes the step (S01, S02) of forming a magnet piece that has a plurality of groove portions that are provided on at least one of end surfaces of the magnet piece in a predetermined direction, the step (S03) of stacking a plurality of formed magnet pieces so that adjacent magnet pieces contact each other and the plurality of groove portions of one of the adjacent magnet pieces cross with the plurality of groove portions of another one of the adjacent magnet pieces, and the step (S04) of inserting and disposing the plurality of stacked magnet pieces into a hole formed in a rotor core.
