A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member includes performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy conditions A and B, applying an adhesive to the surface of the first member to form an adhesive layer on the surface, and adhering the second member to the adhesive layer. (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by DSC of the crystallizable thermoplastic resin. (B) The high temperature holding time of the first member is less than 3.0 seconds, which is when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by DSC of the crystallizable thermoplastic resin.
