A robot hand which can be formed in the shape of a human hand and improves maintenance performance, and generates fingertip force is provided. A robot hand () of the present invention is provided with a hand section () and an arm section (). The hand section () corresponds to the portion of a human hand which is forward from the wrist thereof. The arm section () is provided with a drive device (d) including a plurality of motors and generates driving torque for driving each movable section of the hand section (). The hand section () and the arm section () are configured in such a manner that a group (g) of wrist-mounted pulleys which are first driving torque transmitting members coaxially arranged and a group (r) of arm pulleys which are second driving torque transmitting members coaxially arranged transmit driving torque generated by the drive device (d) to each movable section of the hand section () via gears meshing with each other.
