摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a rolled film base material as a principal object by which a rolled film base material free from dimensional shift in inside and outside of the roll can be obtained.SOLUTION: This method for manufacturing a rolled film base material includes a step of: preparing a rolled film base material by winding up a space member-laminated film base material with a space member arranged on a film base material; and a step of preserving the rolled film base material under an atmosphere of prescribed temperature and humidity until the moisture content of the rolled film base material reaches the moisture content under the atmosphere.
