PROBLEM TO BE SOLVED: To provide an outstanding heat retaining property and upgrade pliability and bulkiness by forming a nonwoven fabric sheet of a nonwoven fabric layer and a abrasive grain layer applied to the surface of the nonwove fabric layer. SOLUTION: A abrasive grain layer 20 is applied to one of the faces of a nonwoven fabric layer 10 and a hydrophilic fiber layer 14 is arranged on the grain layer 20 side, and at the same time, a hydrophobic fiber layer 12 is arranged on the surface of the opposite side. On the surface of the hydrophobic fiber layer 12, recesses 16 are formed at a specified interval and continuously in the orthogonal direction with the surface, forming a striped uneven pattern on the surface of the nonwoven fabric sheet. Further, the recesses 6 are likewise formed on the back face side opposite to the recesses 16 of the first surface, and the hydrophobic fiber layer 12 and the hydrophilic fiber layer 14 are firmly bound together at the spots of the recesses 16 by entangling the fibers mutually. Thus it is possible to impart a heat retaining property, pliability and bulkiness.
