PROBLEM TO BE SOLVED: To prevent easy severance of electric wire and facilitate wiring arrangement of the electric wire by saving electric wire in an articulated industrial robot. SOLUTION: A first arm 4 and a second arm 6 are connected in revolute joint parts 3, 5 and 7. The first arm 4 is rotated by a motor 33 of the revolute joint part 3. The second arm 6 is rotated by a motor 53 of the revolute joint part 5, and a robot hand 8 is rotated by a motor 73 of the revolute joint part 7. Each motor 33, 53 and 73 is respectively driven by control circuit parts 11, 12 and 13, and a control signal and electric power are supplied by a control line 21 and a power line 22 from a control circuit part 20 arranged in a base part 2 interior and controlling a whole of the robot 1 to each control circuit part 11, 12 and 13. By this, the only electric wires drawn from a base part 2 are the control line 21 and the power line 22.
