Abstract
The method for forming a laminate of the present invention is a method for forming a laminate, comprising a silane coupling agent treatment step of applying an aqueous solution of a silane coupling agent onto a surface of a metal layer, and drying the resultant applied film to form a silane coupling agent coating, and a lamination step of laminating a resin layer on the silane coupling agent coating, these steps being continuously performed, wherein when the formed silane coupling agent coating is analyzed in the silane coupling agent treatment step by FT-IR with a reflection absorption spectrometry and then the peak area of Si—O is turned to a value less than a predetermined threshold value, at least one part of the aqueous solution of the silane coupling agent is renewed, thereby conducting the silane coupling agent treatment while the peak area is controlled into a predetermined range.
