Provided is a method for winding a long substrate in which a banded pattern does not readily occur in both end portions of a wound long substrate. A method for winding a long substrate, for winding a long resin film or other long substrate conveyed in roll-to-roll fashion on a cylindrical winding core, wherein both end parts in the width direction of the long substrate are wound so as to be positioned farther from a central axis of rotation of the winding core than a center part in the width direction, preferably 50-200 [mu]m farther at a distal end part of the long substrate wound first in contact with an external peripheral face of the winding core during winding of the long substrate on the winding core.
