Discharge ports of a supply nozzle are structured to be able to discharge a processing solution in a horizontal direction, and a guide plate for reducing the discharge pressure of the processing solution and guiding the processing solution to an under substrate is provided at a position facing the discharge ports. Thus, the appearance of micro bubbles at the time of the supply of the processing solution to the surface of the substrate can be inhibited, thereby reducing poor developing.
