As for this invention, bond strength is high, at the same time, the systematic connection film deposition where the biocompatibility is high and that its production manner is offered are designated as topic. The gelatin and numerator for building a bridge integrating, being the systematic connection film deposition which becomes, the aforementioned gelatin provides the amino group for the side chain, the molecular weight of 50,000 or more and is the gelatin of 100,000 or less, the numerator for aforementioned building a bridge can solve aforementioned topic the active ester basis of 2 or more or by using the systematic connection film deposition which has possessed the Acid anhydride.本発明は、接着強度が高く、かつ、生体親和性の高い組織接着膜及びその製造方法を提供することを課題とする。ゼラチンと架橋用分子とが集積されてなる組織接着膜であって、前記ゼラチンは、その側鎖にアミノ基を備え、分子量が50,000以上、100,000以下のゼラチンであり、前記架橋用分子は2以上の活性エステル基または酸無水物を有している組織接着膜を用いることによって前記課題を解決できる。
