ABSTRACT:
A solution casting apparatus includes a drive roller as a conveying means. The drive roller conveys a polymer film peeled from a belt, the polymer film still containing a solvent. The drive roller has corrugation valleys and corrugation peaks formed on a peripheral surface along a circumferential direction of the drive roller. Each of the corrugation valleys and the corrugation peaks has a substantially semicircular cross section. The corrugation valleys and the corrugation peaks are disposed alternately in an axial direction of the drive roller. A pitch Pvbetween the corrugation valleys and a pitch Pmbetween the corrugation peaks are in the range of 0.01 to 2 mm, and a height Hv-mfrom a lowest point of the corrugation valley to a highest point of the corrugation peak is in the range of 0.01 to 1 mm. A curvature radius Rvof the corrugation valley and a curvature radius Rmof the corrugation peak are in the range of 0.1 to 0.5 mm.
