The present invention addresses the problem of providing: a tissue adhesive film having high adhesive strength and high biocompatibility and a method for producing the tissue adhesive film. This problem can be solved by using a tissue adhesive film comprising an integration of gelatin and cross-linking reagents, wherein the gelatin is provided with an amino group on the side chain thereof and has a molecular weight of 50,000 or higher and 100,000 or lower, and the cross-linking reagents have two or more active ester groups or an anhydride.
