PROBLEM TO BE SOLVED: To provide a coagulating agent comprising two kinds of cross-linking water-soluble ionic polymers and its usage, especially a coagulating agent solving the problem of reducing the loadings while retaining the advantages of the cross-linking polymers. SOLUTION: The agent comprises a vinyl polymer type cross-linking water-soluble ionic polymer of a charge inclusion rate of≥35% and a vinyl polymer type cross-linking water-soluble ionic polymer of a charge inclusion rate of 5-35%.
