A surface sheet material for wound dressing can maintain a moist environment, and is capable of holding exudate on a wound surface as not to expand the area of a would site. In addition, the surface sheet material for wound dressing can be easily removed from the wound surface without producing redness, heat rash, or the smell, and also can adapt to various shapes of wound surface. The sheet material having a permeable liquid layer (1) is used in contact with the wound site (15). The permeable liquid layer is made of a resin surface sheet material (10). The surface sheet material (10) comprises a first surface (11) in contact with the wound site (15), a second surface (12) being the opposite side of the first surface (11) and a plurality of penetration pores (13) penetrating two surfaces (11, 12) in a thickness direction. The penetration pores (13) allow liquid to permeate through the first surface (11) side to the second surface (12) side of the permeable liquid layer. The first surface (11) is hydrophobic.本發明的創傷被覆材用片材及創傷被覆材,其能一邊維持濕潤環境,一邊捕捉滲出液而使其不至於擴大面積,而且使用後容易進行剝離,沒有發紅、汗疹或異臭的產生,能適應於種種形狀的創傷面。該片材在以面對創傷部位(15)之方式使用之側,具備透液層(1)。透液層(1)係由樹脂製的表面片材(10)所成。表面片材(10)具有:面對創傷部位(15)的第1表面(11);與此為相反側的第2表面(12);以及跨越兩表面(11、12)向厚度方向貫穿的多數個貫穿孔(13)。貫穿孔(13)容許液體由第1表面(11)側向第2表面(12)側穿透。第1表面(11)具備疏水性。1‧‧‧透液層2‧‧‧透液限制層3‧‧‧吸收保持層4‧‧‧保護層5‧‧‧創傷被覆材10‧‧‧表面片材11‧‧‧第1表面12‧‧‧第2表面13‧‧‧貫穿孔14‧‧‧儲留空間17‧‧‧凹部
