Abstract: A rotor of a rotational electric motor including a core formed from laminated magnetic steel sheets, and a plurality of magnet arrays extending in a laminating direction of the core is provided. Magnets forming each of the plurality of magnet arrays are selected from first magnets and second magnets. A ratio of the length of the first magnet to that of the second magnet is one to two. The magnet arrays are arranged such that they include at least two of the second magnets and boundary planes between the magnets are offset relative to each other so as not to coincide with each other in a direction perpendicular to the laminating direction.
