Abstract: An imprinting method carries out imprinting on a workpiece by clamping UV-curable resin between a nano-imprinting mold and a workpiece and curing the UV-curable resin using UV light. In this method, the workpiece is supported on a setting table provided with through-holes that are disposed in a planar region of the setting table on which the workpiece is set and are connected to a gas pumping/evacuating mechanism. The UV-curable resin is supplied onto the workpiece and the setting table is raised to and stopped at a filling operation position where the mold surface of the nano-imprinting mold and the surface of the workpiece are apart. After this, gas is pumped toward the lower surface of the workpiece from the through-holes and the workpiece is pressed onto the nano-imprinting mold from a center of the workpiece toward a periphery of the workpiece while gradually filling the UV-curable resin between the nano-imprinting mold and the workpiece.
