After this, for example, a coating liquid for forming a metal oxide film is dropped from the liquid drop nozzle onto the surface of the object to be processed W, the object to be processed W is rotated at high speed by driving the motor 6, and the surface of the object to be processed W is metal oxide. The coating liquid for forming a film is diffused in a uniform thickness. Then, in the above coating step, the liquid scattered from the surface of the object W to be processed by centrifugal force or the like flows down to the bottom surface of the drainage space S1 along the inner surface of the casing 1 and the outer surface of the inclined partition wall 13 and is drained by the inclination of the bottom surface. It flows to the hole 16 and is discharged through the drain pipe 17. Here, since the suction hole 14 formed in the inclined partition wall 13 is covered with the eaves portion 15 above it, the cleaning liquid flowing out from the nozzle 20 does not enter the exhaust air S2 through the suction hole 14. Further, since the suction hole 14 is located above the bottom surface of the drainage space S1, the liquid that has flowed down to the bottom surface does not enter the exhaust space S2 through the suction hole 14.

On the other hand, mist containing fine liquid particles exists in the exhaust space S2. This mist is introduced into the exhaust space S2 through the suction hole 14 and discharged through the exhaust pipe 19. Since the eaves portion 15 is located above the suction hole 14, the inclined partition wall 13
The mist that rises along is blocked by the eaves portion 15, and fine particles do not adhere to the surface of the object W to be processed.
