PROBLEM TO BE SOLVED: To provide a horizontal multi-joint robot capable of loading and extracting a workpiece without using a linear motion mechanism and at the same time of contributing to low dust production and space saving, and a transportation apparatus including the same. SOLUTION: There are provided an end effector 20, a first arm 30, a second arm 40, and further a third arm 50, wherein a workpiece is loaded and extracted by rocking and rotationally operating the third arm 50 so that, for example, a third rotation axis N3 is located on an extension of an axis P1a in an access position P1 and then the end effector 20 is moved linearly.
