Provided is a mold (100) that has: a flexible high-molecular film (12); a hardening resin layer (14) formed on the surface of the high-molecular film (12); and a porous alumina layer (20) formed on top of the hardening resin layer (14). The surface of the porous alumina layer has an inverted moss-eye structure that has a plurality of concavities having two-dimensional sizes, as seen from the direction of the surface normal, of at least 10 nm and less than 500 nm. Also provided is a method for easily manufacturing flexible moss-eye molds that can be deformed into rolls.
