Abstract
An antiadhesive material that is excellent in biocompatibility and bioabsorbability, as well as excellent strength in suturing and bonding, is provided. A reinforcing material 12 made of a biodegradable polymer is placed in a gelatin solution so that the reinforcing material 12 is impregnated with the solution, and the gelatin is caused to gelate and dried. By so doing, an antiadhesive material in which a gelatin film 11 and the reinforcing material 12 are integrated is obtained. The reinforcing material 12 preferably is arranged in a portion of the gelatin film 11 to be subjected to suturing, and preferably is arranged along a periphery of the gelatin film 11. The gelatin film 11 preferably is a cross-linked gelatin film, and the reinforcing material 12 preferably is a nonwoven fabric.
