To provide a robot hand stably gripping an object.
A robot hand of the present invention has a palm link 20 and a plurality of finger links 10 connected to the palm link. A gripping surface is formed of a material having flexibility in at least a part of a surface for gripping an object in a finger link 10 and a palm link 20, and on the gripping surface, a friction coefficient of the gripping surface of the palm link is set to be 1.7 or less, and the friction coefficient of the gripping surface of the palm link is set to be not more than the friction coefficient of the gripping surface of the finger link. Fine irregularities are formed on the surface of the gripping surface, to adjust the friction coefficient. The finger link 10 has a root side link 11 connected to the palm link 20 and a finger tip side link 12 connected to the root side link 11.
