    摘要: PROBLEM TO BE SOLVED: To provide a bioabsorbable material for filling bone defects, which is a flocculent three-dimensional structure having a system for releasing chemical compositions so as to effectively deduce bone reconstruction capability and having flexibility that improves fitting to an affected part, and also expected to show high cell invasion efficiency, and provide a method of producing the same.SOLUTION: A substance containing a biodegradable resin as a principal component and further containing a siloxane is dissolved in a solvent, and spinning is performed according to the electro-spinning method using a solution adjusted to a viscosity to generate a fibrous substance having the average diameter of 10 μm or more. This spinning is performed with air blowing to thereby generate the flocculent three-dimensional structure formed of fibrous substance containing a biodegradable resin as a principal component, further containing a siloxane and having the average diameter of 10 μm or more. The flocculent three-dimensional structure is expected to show high cell invasion efficiency, because a two-dimensionally structured non-woven fabric shows high cell invasion efficiency when it has an average diameter of 10 μm or more.
