A fibrinogen preparation is provided which has an improved solubility, may be prepared within a short time and may be used rapidly in clinical set-up. A solid fibrinogen preparation comprising as a main ingredient fibrinogen and further containing the following components: albumin; a nonionic surfactant; a basic amino acid or a salt thereof; and at least two amino acids or a salt thereof selected from an acidic amino acid or a salt thereof and a neutral amino acid or a salt thereof. The solid fibrinogen composition of the present invention may be held on a medical material to form a supporting material holding fibrinogen. Besides, the supporting material holding fibrinogen may be combined with a component comprising as a main ingredient thrombin to provide a fibrin adhesive.
