<p>In a rotor (100) of a rotary electric machine, a rotor core (30) is formed by helically winding a material sheet (1, 2). The material sheet (1, 2) forms teeth (11) on a first side of a middle connecting portion (15) and projections (21) projecting from a second side of the connecting portion (15) in a direction opposite to the teeth (11). The material sheet (1, 2) is one of a pair of material sheets (1, 2) formed in a single base sheet (10) in a form of belt. In the base sheet (10), the material sheets (1, 2) are arranged such that the projections (21) are intermeshed with each other. The material sheet (1, 2) is helically wound such that the projections (21) are located at an inner diameter side of the rotor core (30). <IMAGE></p> |
