A magnet insertion method into a rotor core is to insert an assembly into a magnet insertion hole provided in the rotor core of an electric motor, the assembly being formed by laminating a plurality of members, including at least a plurality of magnet pieces, in a line. According to this magnet insertion method, the assembly is formed by arranging a front member, having a surface surrounded by a chamfered ridge line, to cause the surface to be a front side end surface upon insertion, by laminating, on its rear side in an insertion direction, other members, without having the chamfered ridge line, in a line along the insertion direction to cause the other members to be hidden inside a projection of the front member when being projected from an insertion hole side, and by temporarily holding the front member and the other members. |
