[Solution] A surface sheet 3 comprises a multilayer structure that includes: a non-thermally-fused layer 10 which comprises cellulose-based fibers disposed on the skin side; and a thermally-fused layer 11 which comprises heat-fusible long fibers disposed on the non-skin side. A second sheet 6 comprising heat-fusible fibers is disposed on the non-skin side of the surface sheet 3. Numerous compressed portions 15… obtained by integrally indenting the second sheet 6 and the surface sheet 3 toward the skin side are formed on the non-skin-side surface of the second sheet 6. The non-thermally-fused layer 10 and the thermally-fused layer 11 are bonded together as a result of having the fibers of the respective layers interlace with each other. The second sheet 6 is configured to have a lower basis weight and a lower density than those of the thermally-fused layer 11. The compressed portions 15 are formed so as to comprise an intermittent pattern or a linear pattern.
