PROBLEM TO BE SOLVED: To enable the product inspection of a resin laminate consisting of two kinds of different resin, to elucidate causes for defects found therein, and to determine the long-term reliability of the resin laminate. SOLUTION: By exposing the resin laminate comprising a resin layer (A) consisting of a resin (a) and a resin layer (B) consisting of a resin (b) of different kind from the resin (a) to the solvent capable of selectively dissolving the resin (a), and the resin layer (B) left behind is analyzed, or the obtained solution is analyzed. When manufacturing the resin laminate, a part of the manufactured resin laminate is sampled during its manufacturing step, and a step of carrying out an inspection step of the product is performed.
