Being the mixture which consists of with the fiber compact and the fibrin paste, being the fiber which consists of the biodegradation characteristic polymer to which the fiber compact includes the phosphatide, fineness of the fiber surface is 1.07 or less and the phosphatide 10 weight % it consists of the fiber which is contained from 0.1 vis-a-vis the biodegradation characteristic polymer. This invention, strength being high, offers the fibrin paste which is superior in organizational adhesiveness and the mixture which consists of the biodegradation characteristic fiber compact.繊維成形体とフィブリン糊とからなる複合体であって、繊維成形体がリン脂質を含む生分解性ポリマーよりなる繊維であって、繊維表面の平滑度が1.07以下でありそしてリン脂質を生分解性ポリマーに対して0.1から10重量%含有する繊維よりなる。本発明は、強度が高くて組織接着性に優れたフィブリン糊と生分解性繊維成形体からなる複合体を提供する。
