The slits 11 of the slit non-woven fabric layers 10S1 and 10S2 expand in the perpendicular direction in respect to its lengthwise direction when a tension perpendicular to the lengthwise direction of the slits 11 is applied, then the circumference of the expanded slits 11 arises up in a vertical direction in respect to a surface direction of the slit non-woven fabric layers 10S1 and 10S2.SELECTED DRAWING: Figure 1
