In a robot hand, at least one finger link thereof is configured to comprise a first member, a second member adhered to a surface of the first member and a third member covering at least the second member and a rigidity of the second member is made smaller than the rigidities of the first member and the third member. With this, the flexibility of the finger is improved by the second member, thereby increasing the contact area between the third member and a held object, so that the object can be securely held.
