To provide an embedded magnet type motor for reducing a leakage magnetic flux.
Receiving holes of a rotor core 8 having P magnetic poles are formed with P/2 radial receiving holes 8a radially extended, and P/2 V-shaped receiving holes 8b (a pair of magnet receiving sections 8f) radially and outwardly protruded. One magnetic pole is composed by a magnet 9 received in the radial receiving hole 8a, and a magnet 10 received in the magnet receiving section 8f circumferentially adjacent to one side of the magnet 9. The other different magnetic pole is composed by the magnet 9 received in the radial receiving hole 8a, and the magnet 10 received in the magnet receiving section 8f circumferentially adjacent to the other side of the magnet 9. P/2 pre-lamination radial receiving holes corresponding to the radial receiving holes 8a in a core sheet 11 comprise: short holes 11a for radially and inwardly short so as to regulate a radial and inward movement of the magnet 9; and long holes 11b radially and inwardly longer than the short holes 11a. The rotor core 8 is formed by laminating the core sheets 11 so as to dispose the short hole 11a in an axial portion of the radial receiving hole 8a.
