In a shaped sheet manufacturing method, it is possible to reliably shape a first sheet even if the tension of the first sheet is reduced at the time of manufacturing the shaped sheet. In a first step, a first sheet is conveyed along an outer peripheral surface of a first roll having a plurality of recessed parts. In a second step, a second sheet is overlapped with the first sheet and conveyed together with the first sheet so that the first and second sheets are held between the recessed parts of the first roll and projection parts of a second roll. In a third step, the first and second sheets having passed between the first roll and the second roll are bonded to each other. In the second step, the tension of the first sheet is made smaller than the tension of the second sheet.
