ある。In order to improve the liquid return preventing property, a technique of using a hydrophobic sheet having openings formed in a surface material as a surface material has been conventionally used (Japanese Utility Model Application Laid-Open No. 54-1).
24398, JP-A-57-1340, JP-A-61-45753) and a perforated film having a capillary structure (JP-B-57-17081, JP-A-60-17081).
Japanese Patent Application Laid-Open No. 259261/1992 and Japanese Patent Application Laid-Open No. 1-249052) have been proposed. However, in these techniques, when an opening area is increased in order to provide a sufficient liquid permeability, the absorber passes through a large opening portion. There is a problem in that the shielding property is poor because it is visually observed, which gives a user a visual discomfort.

When the surface material of this embodiment is used as the surface material of the sanitary napkin, the liquid on the surface material 1 (the liquid on the skin side of the human body) enters the recess 10 and the bottoms 13a, 13a.
b is absorbed by an absorber (not shown) through the openings 14a and 14b formed in the b. In this case, the liquid introduced into the recess 10 is quickly introduced into the openings 14a, 14b of the bottoms 13a, 13b and passes therethrough, so that the top 1a of the surface material 1 that comes into contact with the human body is always kept in a dry state. .

Since only part of 13b is used, the shape retention of the concave portion 10 in the surface material 1 is excellent, so that it is not easily crushed, and the ability to suppress the liquid return of the absorbing liquid under pressure is improved. Therefore, by reducing the area efficiency of the opening portion, it is possible to improve the mold holding property of the concave portion and to improve the liquid return suppressing force under pressure.
