Abstract: Disclosed is a film which is able to suppress agglutination by being continuously adhered to an adhesion target portion in a biological body while suppressing a position shift. A film includes an adhesive and an adhesion inhibiting layer. The adhesive layer absorbs and maintains a liquid in a plurality of pores which are opened in one film surface and has a capillary force for adhering the adhesive layer to a first-cell group. The adhesive layer is formed of a biodegradable polymer. The adhesion inhibiting layer configures the other film surface, and inhibits adhesion between a second-cell group which is different from the first-cell group and the adhesive layer. In the adhesive layer, the pore is formed not to be penetrated in a thickness direction of the film, and thus the first-cell group and the second-cell group are separated into the one film surface side and the other film surface side.

Abstract: Artificial dermis for transplantation includes a wound contact layer that includes a porous sheet consisting of a biodegradable material, the porous sheet satisfying the following Equation, Equation: X2/X1?0.8. In the porous sheet, when a line parallel to a wound contact face and a line perpendicular to a wound contact face of equal length are drawn, X1 represents a number of points of intersection between the line parallel to the wound contact face and pore walls; and X2 represents a number of points of intersection between the line perpendicular to the wound contact face and pore walls.
