This manufacturing device (100) comprises: an embossing roll (7) having, on a circumferential surface (7f), a compressed line groove formation projection (60) that has a high-pressure part (60s) and a low-pressure part (60w) and that forms a compressed line groove (6)； and an anvil roll (8). The embossing roll (7) has, in a region sandwiched by convex projections adjacent in a (Y) direction on the surface (7f) or in a region surrounded by convex projections on the surface (7f), a tension suppression part (9) that suppresses tension of a surface sheet (2) when forming the compressed line groove (6). The tension suppression part (9) protrudes upward from the surface (7f) of the embossing roll (7) to a position lower than the low-pressure part (60w) of the projection (60).
