Where the length LD of a resin film forming region is, for example, 3 times as long as the pitch of the sprocket holes of the base film, the resin coating is performed by using 6 nozzles, and where the length LD is, for example, 6 times as long as the pitch of the sprocket holes, the resin coating is performed by using 3 nozzles. As a result, the transfer distance of the base film transferred in a single resin coating process is 18 times as long as the pitch of the sprocket holes. It follows that it is possible to set constant the time for the base film to pass through the drying section even if the length LD of the resin film forming region differs.
