Provided is a rotor 10 capable of avoiding an increase in cost due to use of a high-performance winding machine and an increase in cost due to molding of the entire rotor 10 with an insulator, and a rotating machine including the rotor 10. The rotor 10 includes a rotor core 11 that rotates around a rotary axis A. The rotor core 11 includes a plurality of unit through holes 11a that individually accommodate each of a plurality of winding units 12. Each of the plurality of winding units 12 includes an iron core, a field winding wound around the iron core, and an insulating sealing resin that seals the iron core and the field winding, and is accommodated in the unit through hole 11a in a posture extending in a direction of the rotary axis A.
