<P>PROBLEM TO BE SOLVED: To provide a sheet-like structure effectively usable as a wound covering material or the like, having high strength and excelling in biocompatibility. <P>SOLUTION: This sheet-like structure is formed of a water-insoluble polymer having carboxyethyl cellulose in a molecular chain skeleton. In the structure, tensile strength, piercing strength and thickness in a dry condition are ≥1,000 g/mm<SP POS="POST">2</SP>, ≥20 kg/mm and 5 to 10,000 μm, respectively, and tensile strength, piercing strength and thickness in a swollen state by water are ≥50 g/mm<SP POS="POST">2</SP>, ≥1.0 kg/mm and 50 to 15,000 μm, respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
