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.
