PROBLEM TO BE SOLVED: To obtain a resin molded article which does not evaporate an odor during its employment, can be scrapped by simply method after used, has a low density, and is useful as a raw material for industrial design models. SOLUTION: This biodegradable resin molded article useful as a raw material for models is obtained by kneading and molding (A) a thermoplastic urethane resin prepared by reacting (a) an active hydrogen component containing >=10 wt.% of (a1) a linear aliphatic polyester diol having a hydroxy value of 10 to 250 and a softening temperature of <=100 deg.C with (b) an aliphatic polyisocyanate, (B) a filler, (C) a solubilizing agent, and (a1) the component.
