<P>PROBLEM TO BE SOLVED: To provide a medical sheet-like covering member which is obtained by subjecting the surface to hydrophilic treatment and/or a coating treatment by a composition containing calcium phosphate ceramics or a biopolymer material so as to obtain early and firm adhesion to biological tissues. <P>SOLUTION: This covering member mainly composed of organic polymers is preferably shaped in a flexible sheet made of a fiber material, a porous material, or a material with an uneven surface, being ≤5 mm in thickness and 100 cm<SP>2</SP>or larger per gram in specific surface area. To the surface of the polymeric material, is applied with a treatment for giving substantially enough hydrophilicity, a coating treatment with a composition containing calcium phosphate ceramics or a biopolymer material, or a coating treatment with the composition after the hydrophilic treatment is applied as a pre-treatment. <P>COPYRIGHT: (C)2007,JPO&INPIT |
