Provided is a headrest able to attain, with a simple configuration, properties for damping vibrations at two resonance frequencies. Also provided is a vehicle seat that is equipped with the headrest. A mass (34) is supported by an elastically deformable first urethane material (30), which constitutes a portion of a headrest pad (20), on the inner side of the headrest skin of the vehicle seat (10). That is, a dynamic damper (28) equipped with the first urethane material (30) and the mass (34) is constructed. The centroid (34G) of the mass (34) is set at a position that is offset from the elastic center (30C) of the first urethane material (30) in the width direction of the seat.
