Beschreibung
Zusammenfassung:	An apparatus for treating a substrate includes a processing container having an inner space; a support unit having a support plate configured to support and rotate the substrate in the inner space; a liquid supply unit configured to supply treating liquid to the substrate supported by the support unit; and an exhaust unit configured to exhaust an air flow in the inner space, wherein the exhaust unit includes an air flow guide duct guiding a flow direction of an air flow flowing on the substrate to an outer side of the substrate due to a rotation of the substrate supported by the support unit, and the air flow guide duct having an inlet into which an air flow is introduced, the inlet provided at a substantially same level with the substrate supported by the support unit.
