Abstract (en)
An object of the present invention is to provide a biodegradable three-dimensional network structure having excellent compression durability and high compression recovery after heat compression. The biodegradable three-dimensional network structure includes a linear fiber including a polybutylene adipate terephthalate resin having a weight average molecular weight of 35000 or more, wherein the biodegradable three-dimensional network structure has an apparent density of from 0.005 g/cm<sup>3</sup> to 0.30 g/cm<sup>3</sup> and a thickness of from 10 mm to 100 mm, and the linear fiber has a fiber diameter of from 0.2 mm to 2.0 mm and a crystalline melting enthalpy of 16 J/g or more.
