Claim Text:
1. A minute convexo-concave pattern forming method comprising: a transferring step of transferring a minute convexo-concave pattern of a mold to a resist layer of a transfer substrate and curing the transferred minute convexo-concave pattern; and a peeling step of, after the transferred minute convexo-concave pattern are cured, peeling apart the transfer substrate and the mold, the peeling step including: a first peeling step of pressurizing a substrate back surface side of the transfer substrate with a peripheral part of the transfer substrate being fixed to bend the transfer substrate in a curved shape, and starting peeling of the transfer substrate and the mold with a bending of the transfer substrate; and a second peeling step of peeling a part of the minute convexo-concave pattern of the transfer substrate not peeled in the first peeling step by gradually decreasing a pressure for a pressurization so as to restore an original shape of the transfer substrate, wherein, in the first and second peeling steps, a load applied to the transfer substrate is measured, and the pressure on the substrate back surface side is controlled based on the measured load.
