The abstract states:

A medical film that is excellent in biocompatibility and bioabsorbability and has an excellent strength in suturing and bonding is provided. A reinforcing material 12 made of a biodegradable polymer is placed in a gelatin solution so as to allow the solution to infiltrate in the reinforcing material 12 and then the gelatin is dried. This allows the gelatin that has infiltrated entirely in an internal part of the reinforcing material 12 to gel, thereby forming a gelatin film 11. Thus, a medical film 1 in which the reinforcing material 12 and the gelatin film 11 are integrated is obtained. The gelatin film 11 preferably is a cross-linked gelatin film.
