摘要：
To provide a scaffold for tissue engineering which consists of a bioabsorbable polymer material to be absorbed in a biotissue, and holds strength of the whole scaffold while having a porosity proper for culturing cells inside thereof as well, a method for producing the scaffold for tissue engineering includes steps of dissolving a bioabsorbable polymer material with an organic solvent, drying the solution so as to produce a porous bioabsorbable polymer material having a porosity of 50 to 99%, covering the porous bioabsorbable polymer material with a bioabsorbable polymer material having a thickness of 0.01 to 5 mm, pores of 10 to 3000 μm diameter, a fracture strength of 0.05 to 0.15 MPa, and a volume of 15 to 90% with respect to the whole scaffold.
