Provided is an anti-adhesion material that can be reliably attached to a living tissue and has improved tissue adhesion and biodegradability. Anti-blocking material comprising a water-soluble support layer containing a water-soluble polymer having a thickness of 1 to 1000 μm, and an anti-blocking layer containing a biodegradable polymer and having a thickness of 1 to 1000 μm, the biodegradable polymer having a branched chain The structure formed by the bonding of polyalkylene glycol and polyhydroxyalkanoic acid, and the mass ratio of the branched polyalkylene glycol to the total mass is 1~30%, and the branched polyalkylene glycol The alkyl glycol has 3 to 8 terminal hydroxyl groups per molecule. |
