PROBLEM TO BE SOLVED: To make effectively reusable coffee extract residue and tea grounds to manufacture an inexpensive throwaway sanitary sheet by sequentially stacking a non-woven fabric layer, a water impermeable film part, plural paper layer parts and a water absorptive layer part, and making dried material of a coffee extract remaining waste liquid contained in the non-woven fabric layer part. SOLUTION: The sanitary sheet 1 is so constructed that the base part is formed by a water impermeable film layer part 2, a water absorptive paper layer part 3 is formed thereon, and a water absorptive layer part 4 is formed by a waste powder pulverized powder containing high water absorptive resin amount thereon. Further, another water absorptive paper layer part 5 is arranged thereon, and a water permeable non-woven fabric layer part 6 impregnated with exudation liquid or percolation liquid of prepared coffee extract residue or exudation liquid or percolation liquid of tea grounds of oolong tea witch the above is formed to cover the part 5. The end part of the non-woven fabric layer part 6 is made adhere to or joined to the end part of the water impermeable film layer part 2 to form the sanitary sheet 1. Further, both water absorptive paper layer parts 3, 5 and the water absorptive mixing layer part 4 are superposed one another to be embossed. |
