The present invention, also becomes long, the length of the hand, and to provide an industrial robot capable of to shorten the tact time in the production system in which the industrial robot used and, hand or arm, such as the miniaturization of the transfer chamber disposed therein. Industrial robot (1), hands (12, 13), arm support is to be the proximal end side of the pivotably connecting arms (14, 15) and the arm (14, 15) to the front end side is rotatably connected (16) and, and the support arm 16 is provided with a body portion 18 which is the base end side is rotatably connected in the swing arm 17 is pivotably connected to the front end side and the swing arm (17). Assuming that the main body portion 18, the swing arm 17, the rotating center arm pivoting of the center C4 of the arm (14, 15), the swing arm 17 when the pivot, which rotates together with the swing arm (17) the maximum radius of rotation of the arm rotating center C4 of the part is carried out so as to reduce the elastic behavior.
