Zusammenfassung:	An object is to provide a water-dispersible paper that exhibits excellent dispersibility in water. As a solution, a water-dispersible paper is provided, which has: a base paper that has a bulky layer containing 10% by weight or higher of a softwood pulp with a lumen width (l) to fiber diameter (D) ratio (l/D) of 0.60 or lower on average; and a water-soluble polymer impregnated into the base paper.
