The purpose of the present invention is to provide a method for producing a laminated polishing pad that is not warped and in which the polishing layer and the cushion layer do not separate at the time of polishing. This method for producing a laminated polishing pad includes: a step for laminating a hot-melt adhesive sheet on a surface of a base-material-equipped cushion layer on which a thermoplastic resin base material, which is peelably provided on one surface of said cushion layer, is not provided; a step for melting or softening the laminated hot-melt adhesive sheet by heating the same; a step for preparing a laminate by laminating a polishing layer on the molten or softened hot-melt adhesive; a step for preparing a laminated polishing sheet by cutting the laminate to the size of the polishing layer; and a step for peeling the thermoplastic resin base material from the laminated polishing sheet. |
