<P>PROBLEM TO BE SOLVED: To provide a sludge dewatering agent composition and a sludge dewatering method which generate solid and drainable flocs, such as flocs generated by the single use of a crosslinked polymer, in various sludges to be dewatered to enable improvement of the amount of treated sludge and reduction of a cake moisture content, and can exhibit the effect with a very small addition amount of the dewatering agent in comparison with the single addition of the cross-linked polymer. Ž<P>SOLUTION: A flocculate generated by mixing and agitating the sludge to be dewatered with the sludge dewatering agent composition combining (A) a crosslinking ionic water-soluble polymer having a charge inclusion ratio of 35% and more and 90% or less, and (B) an ionic water-soluble polymer having a charge inclusion ratio of 3% and more and 15% or less is dehydrated by a dehydrator.
