To provide an industrial robot capable of being reduced in size and of lowering the pass line height.

The industrial robot 1 includes a body section 3, a first arm 4, a second arm 5, a third arm 6, a first speed reducer 21 which connects the body section 3 and the first arm 4, a second speed reducer 22 which connects the first arm 4 and the second arm 5, a connecting mechanism 23 which connects an input shaft 25 of the first speed reducer 21 and an input shaft 32 of the second speed reducer 22, and a second drive motor 40 which drives the third arm 6 into rotation. In the industrial robot 1, the speed reduction ratio of the first speed reducer 21 and that of the second speed reducer 22 are set in such a way that the movement locus of a third articulation section which connects the second arm 5 and the third arm 6 is straight line. Furthermore, the connecting mechanism 23 connects the input shaft 25 and the input shaft 32 at a predetermined speed ratio. Moreover, the second drive motor 40 is mounted on the second arm 5 at a location closer, relative to the third articulation section, to the tip of the second arm 5 in such a way as to protrude toward the first arm 4.
