A rinsing liquid supplier includes a temperature adjuster. The temperature adjuster cools DIW to a temperature lower than room temperature. This temperature adjuster cools down DIW to a temperature not more than 10 degrees centigrade for instance, and cooling down to an even lower temperature of 5 degrees centigrade or below is more preferable. Meanwhile, the temperature adjuster maintains DIW at not less than 0 degrees centigrade, which prevents freezing of the DIW. The cooled DIW supplied to a rinsing liquid pipe is discharged from the rinsing liquid discharge nozzle toward the top surface of the substrate, to thereby form a liquid film. Further, the cooled DIW is discharged toward the rear surface of the substrate from the liquid discharge nozzle via the liquid supply pipe, to thereby form the liquid film on the rear surface. Since the liquid films are already cooled, they are frozen in a short time when the cooling gas is discharged toward the top surface and the rear surface of the substrate.
