摘要
A technique for producing a pressure-sensitive adhesive tape is provided which attains satisfactory coating pattern reproducibility when a pressure-sensitive adhesive is applied with a gravure roll. Partitions (23) which separate cells (21, 22) formed in the surface of a gravure roll (10a or 10b) are disposed at the boundaries between the cells (21, 22), and fine irregularities (24) are further formed in the surface of the partitions (23) in order to improve coating pattern reproducibility.
