Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water disintegrable resin film excellent in water disintegradability while having a definite water resistance and keeping excellent mechanical strength even when exposed under high-temperature and wet conditions at about 40 deg.C. SOLUTION: This water disintegrable resin exhibits a tensile strength of >=2 N/25 mm width after the surface thereof is pressed by a cotton gauze impregnated with water of 40 deg.C with a pressure of 1.47 N/cm for 5 hr under a condition wherein the temperature is 40 deg.C and the relative humidity is 90% and exhibits
