Further, a suction part 62 sucks the first treatment liquid from a portion near an edge of the substrate 9 to enable the coating of the upper surface 91 of the substrate 9 with the first treatment liquid to be performed in a still shorter time. As a result, the time required for the treatment of the substrate 9 can be shortened.
