Abstract

A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.
