Abstract
An antifouling method for polysilicon includes using a tube-shaped resin sheet having an inner surface and an outer surface to prevent the fouling of polysilicon, in which the tube-shaped resin sheet or a resin sheet cut out of the tube-shaped resin sheet is held, with the inner surface being kept in an unexposed state, and the inner surface is exposed just before use and brought into contact with the polysilicon.
