Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a biodegradable molding useful e.g. for bone substitutes, bone cementing materials, bone fillers, dental materials, drug release regulating materials and physiologically active substance release regulating materials and excellent in biocompatibility, bioabsorbability and storage stability, a biodegradable material and a process for producing them. SOLUTION: This invention provides a biodegradable molding wherein water- soluble polymer fibers (B) are contained in a biodegradable polymer (A), and at least one water-soluble fiber B penetrates between at least two faces of polymer A and a biodegradable material which is prepared by removing fibers B by treatment with an aqueous solution and in which at least one hole with a pore diameter of 1-1,000 μm penetrates between at least two faces of polymer A.
