A method for producing a laminated polishing pad, which is free from warpage and does not cause peeling between a polishing layer and a cushion layer during polishing, includes the steps of: laminating a hot-melt adhesive sheet to a surface of a cushion layer with a base material in which a thermoplastic resin base material is provided peelably on one surface of the cushion layer, on which the thermoplastic resin base material is not provided; heating the laminated hot-melt adhesive sheet to be melted or softened; laminating a polishing layer on the melted or softened hot-melt adhesive to prepare a laminate; cutting the laminate to the size of the polishing layer to prepare a laminated polishing sheet; and peeling the thermoplastic resin base material from the laminated polishing sheet. |
