PROBLEM TO BE SOLVED: To provide technology of an industrial robot, enlarging the movable range. SOLUTION: This industrial robot 1 is constructed as a horizontal multi-joint robot, and the robot includes: an arm part 11 connected to a base part 10 through a first joint J1; and a hand part 12 connected to the arm part 11 through a wrist joint part Jh. The arm part 11 includes: a first arm 111 connected to a first joint J1; and a second arm 112 connected to the first arm 111 through a second joint J2. The length L2 of the second arm 112 is larger (e.g. about 1.5 times) than that L1 of the first arm. Thus, when performing horizontal revolving using the first joint J1 with the arm folded at the second joint J2, the ratio of the minimum revolving radius to the maximum reach radius can be reduced so that the movable range of the robot 1 can be enlarged.
