Provided is a sludge dehydration agent which enables the formation of stiff and coarse flocs even when added in a relatively small amount, has excellent gravity filtration properties, enables the production of a dehydrated cake having a low water content, and also enables an efficient dehydration treatment. A sludge dehydration agent comprising a polymer having a constituent unit derived from a cationic monomer, wherein the colloid equivalent value decrease rate of the polymer, which is calculated from mathematical formula 1, is 10% or more. (In mathematical formula 1, the colloid equivalent value (I) is a colloid equivalent value at pH 4 which is measured in deionized water by a colloid titration method, and the colloid equivalent value (II) is a colloid equivalent value at pH 4 which is measured in salt water having a concentration of 0.01 mol/L by a colloid titration method.)
