A loading/unloading robot includes an arm unit attached to a support unit that is capable of being raised and lowered and a hand unit for conveying a loaded/unloaded object, attached to the arm unit. The support unit includes a base portion capable of revolving around a raising/lowering axis and a head portion rotatably attached to the base portion. The arm unit includes arms that are rotatably attached to the head portion. Front ends of the arms move forward and backward along a forward/backward direction that passes the head portion. The hand unit includes a loading/unloading hand rotatably attached to the arm. A center distance from the rotational axis of the head portion to the rotational axes of rear arms is shorter than a center distance from an axis of revolution of the base portion to the rotational axis of the head portion.
