A sulfonate group-containing copolymer is provided which comprising a structural unit (a) derived from a sulfonate group-containing monomer (A); a structural unit (b) derived from a (poly)oxyalkylene monomer (B); a structural unit (c) derived from a carboxyl group-containing monomer (C). The sulfonate group-containing copolymer comprises from 20% to 90% by mass in an acid form equivalent of the structural unit (c) in 100% by mass of all the structural units constituting the sulfonate group-containing copolymer. The product (P×Mw×n) of the ratio by mass P of the structural unit (b) to the structural unit (a) multiplied by the weight average molecular weight Mw of the sulfonate group-containing copolymer multiplied by the value n is from 950,000 to 800,000,000.
