Roller mold, method for manufacturing same, and transfer sheet

The invention provides a roller die, in which a plurality of linear grooves are arranged and formed on the outer peripheral surface, the optical level difference between adjacent linear grooves is sufficiently small. The roller die is provided with n linear grooves which extend in the direction of a roller shaft or in a direction inclined with respect to the direction of the roller shaft on the outer peripheral surface, and is characterized in that the n linear grooves are arranged in a manner that the groove depths gradually decrease and gradually increase repeatedly, and the part where the groove depth transitions from decreasing to increasing is within m (where n is more than 800, and m is selected from 2 to 8). 本发明提供一种辊模具，其在多条线状槽排列而形成于外周面的辊模具中，相邻的线状槽之间的光学阶差充分小。辊模具在外周面具备沿辊轴方向或相对于辊轴方向倾斜的方向排列延伸的n条的线状槽，其特征在于，所述n条线状槽以槽深渐减以及渐增重复的方式排列，并且槽深从减少向增加过渡的部位为m处以内，其中，n为800以上，m选自2～8)。
