A double-sided coated substrate transport device (1) is described. A die head for front face coating (3) and a die head for back face coating (4) coat a coating liquid onto a substrate 1. A drying oven (5) dries the coating liquid applied to the substrate (1), to form coating films on the front and back faces of the substrate (1). A first and second rotating body unit (20A, 20B) are respectively furnished independently at widthwise edge sections of the substrate (1). Each of the first and second rotating body units has a free roller (21) and a drive roller (22) constituting a pair of rotating bodies, and a rotating body swivel section (23). The free roller (21) and the drive roller (22) grip the widthwise edge sections of the substrate (1) from the front and back sides. The rotating body swivel section (23) allows the orientation of the free roller (21) and the drive roller (22), respectively, to be modified separately for the first rotating body unit (20A) and the second rotating body unit (20B), so that the rotation axis of the free roller (21) and the drive roller (22) is inclined towards the downstream side in the substrate transport direction as seen from the outside in the substrate widthwise direction, with respect to a line perpendicular to the substrate transport direction.
