摘要

PROBLEM TO BE SOLVED: To provide a resin molding such as a resin sheet having high liquid repellency on its surface.SOLUTION: A mold 20 is used for forming a resin molding comprising liquid repellency by structure transfer from a transfer surface. The transfer surface comprises plural micro recessed structures 21 formed of recessed parts whose maximum opening diameter is equal to or more than 15 μm and equal to or less than 100 μm. In addition, the transfer surface comprising the surfaces of the micro recessed structures 21 comprises plural nano recessed structures 22 formed of recessed parts whose maximum opening diameter is equal to or more than 50 nm and equal to or less than 1000 nm.SELECTED DRAWING: Figure 4
