What known techniques are compared to provide the sufficient decomposability and the excellent anti-adhesive properties that have in vivo by system of the present invention, and the more excellent anti-material that is adhered of operability when adhesional wetting is its purpose. The present invention it is it is anti-be adhered material (1) system and be made of sheet, have: the base layer (10) containing water soluble polymer (such as poly- tri-glucose)； It is configured in the one side of base layer (10), the 1st coating (20) containing aliphatic ester； And it is configured in the another side of base layer (10), the 2nd coating (30) containing aliphatic ester. The optical thickness system of 1st coating (20) and the 2nd coating (30) is set as 27nm or more and less than 160nm.本發明係以提供具備在生物體內之充分的分解性及優異的抗黏性能，並且相較於習知技術，沾濕時之操作性更為優異的抗黏連材為其目的。本發明之抗黏連材(1)係由片狀所構成，具備：含有水溶性高分子(例如聚三葡萄糖)之基體層(10)；在基體層(10)的一側面配置，含有脂肪族酯的第1被覆層(20)；以及在基體層(10)的另一側面配置，含有脂肪族酯的第2被覆層(30)。第1被覆層(20)及第2被覆層(30)的光學厚度係設定為27nm以上且未滿160nm。
