A molded article obtained by blending a poly-functional monomer in a biodegradable polyester, kneading the blend, and molding the kneaded material into a predetermined shape is irradiated with ionizing radiation at an irradiation dose of 50 to 200 kGy to crosslink the biodegradable polyester to a gel fraction of 50 to 90%, where the flexural modulus is from 100 to 400 MPa, and the Young's modulus is from 60 to 240 MPa.
