Abstract

A guard that receives a processing liquid removed off a substrate, is disposed so as to surround a substrate holding unit and a facing member in plan view. The guard forms, together with the substrate and the facing member having a facing surface facing an upper surface of the substrate, a space isolated from an ambient atmosphere. An inert gas supplying unit supplies an inert gas to the space to replace an atmosphere inside the space by the inert gas. A processing liquid supplying nozzle, which extends from an inner wall of the guard so as to be disposed inside the space in a state where the space is formed, supplies the processing liquid to the upper surface of the substrate.
