Opening films used as surface sheets, such as sanitary napkins, have stickiness to the skin, and surface sheets formed of nonwoven fabrics having wavy grooves also have irritation to the skin and are inferior in liquid permeability. Ridges ridges 16 are formed in the surface layer 10 on which the surface sheet 11 and the reinforcement sheet 12 overlap, and grooves 17 are formed to surround the ridges 16 of the ridges. The hole 13 is opened in the groove 17. Therefore, the liquid imparted from the ridge 16 to the groove 17 is quickly absorbed by the hole 13. In addition, since the ridges exhibit cushioning and elasticity independently of each other, the contact with the skin is soft. |
