An inexpensive and compact robot hand and a robot having the robot hand, wherein the robot hand is configured to rotate a cylindrical object gripped by the robot hand and does not negatively affect a cable, etc., connected to the robot hand. N number of fingers are moved by a first drive part so that a circumcircle of a N-sided polygon constituted by the fingers is arranged in a concentric pattern about the center axis of the object. Each first roller is rotatable about an axis parallel to the center axis of the object, and is configured to contact the inner peripheral portion of the object by movement of the finger relative to a hand base. By rotationally driving at least one first roller while a radially outward force is applied to the object, the object may be rotated relative to the hand base.
