The cross-linked polyallylamine or an acid addition salt thereof is obtained by copolymerization of allylammonium dihydrogen phosphate with an acid addition salt of N,N'-diallyl-1,3-diaminopropane in an amount of 5 to 25 mol % with respect to the amount of the allylammonium dihydrogen phosphate, the cross-linked polyallylamine or an acid addition salt thereof having a phosphate adsorption capacity of 2.7 to 5.0 mmol/g; and a degree of swelling of 2.0 to 5.0. The cross-linked polyallylamine or an acid addition salt thereof is useful as a therapeutic or prophylactic agent for hyperphosphatemia.
