NOVELTY - A coating liquid having radiation hardenable monomer or oligomer is coated on base material, to from coating film. The coating film is heated, solvent in coating liquid is dried, hardened, lower layer is formed, and upper layer is formed by forming inorganic film on lower layer, to form laminate. The coating film on base material is processed under pressure (P1) for predetermined time (T1), before carrying out hardening process. The coating film on base material is processed under pressure (P2) more than the pressure (P1) for predetermined time (T2), during hardening process.    USE - Manufacture of laminate (claimed). Uses include but are not limited to optical filter and optical film such as light reflection preventing film and light reflection film used for display device e.g. liquid crystal display, organic electroluminescent display, semiconductor device and thin film solar cell.    ADVANTAGE - The method suppresses declination of smoothness in the upper surface of laminate.    DETAILED DESCRIPTION - A coating liquid containing radiation hardenable monomer or oligomer is coated on a base material, to from coating film. Then, the obtained coating film is heated and the solvent in the coating liquid is dried, hardened using radiation, a lower layer is formed, and an upper layer is formed by forming inorganic film by vacuum coating process on the lower layer, to form laminate. The coating film on the base material is processed under pressure (P1) for predetermined time (T1), before carrying out hardening process. The coating film on the base material is processed under pressure (P2) more than the pressure (P1) for predetermined time (T2), during hardening process. The coating film on the base material is processed under pressure (P3) less than the pressure (P1) for predetermined time (T3), during vacuum coating process.
