To enable division for transportation and secure proper treatment on a substrate to be treated, the present invention provides a stage apparatus (11) including a substrate holding plane which holds a substrate to be treated, a pair of guide frames (13X1), (13X2) oppositely disposed with the substrate holding plane sandwiched therebetween, and a gantry (13Y) which is movably held on upper surfaces of the pair of guide frames (13X1), (13X2). The stage apparatus (11) is composed of a first structure V1 which includes one guide frame (13X1), a second structure V2 which includes the other guide frame (13X2), and a third structure V3 which includes the gantry (13Y). Thus, even if the stage apparatus is large, since it can be divided into the structures V1 to V3, the stage apparatus can be transported by land. In addition, since there are no joints on a moving path of the gantry (13Y), the stage apparatus can properly treat the substrate without causing deterioration of moving accuracy.
