A mold and a process for producing a base material having a transferred micropattem, wherein the mold comprises a transparent substrate having chemical bonds resulting from functional groups (x) on a surface on which an interlayer (A) is formed, the interlayer (A) present between the surface of the transparent substrate and a surface layer (B) which has a micropattem for molding a photocurable resin, wherein interlayer (A) is a layer made of a fluoropolymer (1) which is a fluoropolymer having a fluorinated alicyclic structure in its main chain and which has reactive groups (y) reactive with functional groups (x), and surface layer (B) is a layer made of a fluoropolymer (2) which is a fluoropolymer having a fluorinated alicyclic structure in its main chain and which has substantially no reactive groups (y).
