Abstract
A peeling method includes a first decompression step, a pressure-heating step, and a second decompression step. In the first decompression step, an object with a skin to be peeled is placed in a pressure chamber being sealed, and an inside of the pressure chamber is decompressed to a predetermined first negative pressure state. In the pressure-heating step, the inside of the pressure chamber is pressure-heated to a predetermined pressure-heating state after the first decompression step. In the second decompression step, the inside of the pressure chamber is decompressed to a predetermined second negative pressure state after the pressure-heating step.
