<P>PROBLEM TO BE SOLVED: To provide a good-looking winding body for winding up a film having a super smooth surface in which a pimple fault caused by a step of a start of winding is suppressed, and wrinkles are also suppressed. <P>SOLUTION: The winding body includes: a core body 1; a winding-up core having a coating layer 2 formed on a surface of the core body; and the film 4 wound around the winding-up core. The surface hardness of the coating layer is not lower than 45 degrees and lower than 60 degrees, and a centerline average surface roughness Ra of the film is equal to or lower than 20 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
