Provided are a rotor of rotating electric machine, and a rotating electric machine, that enable improvement in positioning accuracy for magnets in the circumferential direction. A base portion (16) of a magnet holder (14) attached to a rotor core (12) of a rotor (3) has a press-fit pin (18) press-fitted into a press-fit hole (32) provided at an end surface of the rotor core (12). An arm portion (16) of the magnet holder (14) has a holder rib (21) which protrudes inward in the radial direction of an output shaft (2) and of which one end surface in the circumferential direction serves as a pressing surface (25), and a come-off prevention protrusion (23) inserted into an insertion groove (29) provided at an outer circumferential surface of the rotor core (12). Magnets (13) are located between the rotor core (12) and the magnet holders (14), one end surface in the circumferential direction of each magnet contacts with the pressing surface (25), and another end surface contacts with a core rib (28) protruding from the rotor core (12).
