Provided are a headrest and a vehicle seat provided with same with which load on the vehicle occupant's neck in the event of a rear collision can be reduced while ensuring NV performance. Inside the outer cover (22) of a headrest of a vehicle seat (10), a first mass body (40) and a second mass body (42) are embedded in an elastically deformable headrest pad (20). The first mass body (40) and the second mass body (42) are arranged side by side at a distance from one another on the left and right sides, in the width direction of the seat, with respect to the center line (CL) of the headrest (14) in the width direction of the seat. The product of the distance from the center of gravity of the headrest (14) to the center of gravity (G1) of the first mass body (40) and the mass of the first mass body (40) is set so as to be equivalent to the product of the distance from the center of gravity of the headrest (14) to the center of gravity (G2) of the second mass body (42) and the mass of the second mass body (42).
