PROBLEM TO BE SOLVED: To provide a rotor and a motor capable of reducing the production cost, or a rotor and a motor capable of effectively reducing core loss which can occur at the rotor. SOLUTION: In the inner rotor type motor 1, the rotor 3 is formed, by connecting a separately manufactured outer peripheral section 31 and an inner peripheral section 32 with each other, via permanent magnets 4, The outer peripheral section is manufactured by laminating a magnetic material, capable of reducing core loss, for example, a high grade electromagnetic steel plate. Alternatively, the outer peripheral section can be manufactured by press molding electromagnetic iron powder into a cylindrical shape. In this case, the cylindrical body 5 is fitted to the outer periphery of the permanent magnets 4, The cylindrical body 5 has a plurality of notches 51, formed therethrough that extend in the peripheral direction.
