PROBLEM TO BE SOLVED: To provide a laminating method which can prevent mutual adhesion of adjacent copper-clad laminates with a dry film, and which also can prevent a resist layer not covered by a cover film and exposed in the periphery of the dry film from being separated from the copper-clad laminate and becoming a foreign matter followed by an exposure process eventually causing a defective product. SOLUTION: In this method of laminating a dry film, the periphery 11 of the dry film 1 on the copper-clad laminate 5 which has been subjected to thermocompression bonding by a laminate roll is more rapidly cooled than the central portion 12 of the dry film 1 and is cooled until the temperature becomes 50°C or below.
