PROBLEM TO BE SOLVED: To provide a highly water-absorptive resin being excellent in biodegradability and saline- and seawater-absorption capacities, and its preparation method. SOLUTION: The highly water-absorptive resin satisfies the following conditions: (1) the cellulose or cellulose derivative content is≥50 wt.%; (2) the polymerization degree of the cellulose or the cellulose derivative is 80-1,800; (3) the saline- and seawater-absorbing capacities are≥50 g/g and≥30 g/g, respectively.
