To obtain a biodegradable net having a good balance on the points of shapability, physical properties when used, biodegradability after scrapped, etc., by subjecting a specific component to a radiation irradiation treatment.
This biodegradable net is obtained by shaping (a) a lactone resin such as -caprolactone alone, (c) a lactone-containing resin comprising (a) the lactone resin and (b) one or more other biodegradable resins such as an aliphatic polyester or (e) a lactone-containing resin composition comprising (c) the lactonecontaining resin and (d) one or more resin additives such as a plasticizer (for example, a phthalic ester) and a heat stabilizer (for example, lactic acid). Therein, the lactone resin singly or together with at least one other component as the components of the biodegradable net is subjected to a radiation irradiation treatment. The gel fraction of the lactone resin is 0.01-90%.
