Claim Text:
1. A rotor of a rotating electric machine comprising: a shaft; a pole core provided with a magnetic pole that rotates integrally with the shaft; a bobbin that is fixed to the pole core and includes a winding section, a first flange section and a second flange section provided at opposite axis-direction ends of the winding section, a first latching section and a second latching section provided in such a way as to extend radially outward from the first flange section and the second flange section, respectively, and a first stopper section and a second stopper section provided in such a way as to further extend radially outward from the first latching section and the second latching section, respectively; a magnetic-field coil that is formed of a conductor wire wound around the bobbin and in which a winding-end section of the conductor wire is wound and latched around the second latching section, in which a lead wire drawn from the winding-end section by way of the second latching section is wound and latched around the first latching section, and in which a radial-direction travel of the conductor wire is limited by the first and second stopper sections; and a slip ring that is fixed to the shaft and is electrically connected with a lead wire of the conductor wire, wherein the radial-direction length of the second latching section is shorter than the radial-direction length of the first latching section.
