Abstract
Provided is a dispersant containing a copolymer that includes an aliphatic hydrocarbon structural unit, a nitrile group-containing structural unit, and a substituted or unsubstituted carbamoyl group-containing structural unit. The aliphatic hydrocarbon structural unit includes an alkylene structural unit. The content of the aliphatic hydrocarbon structural unit is 40 mass % or more and less than 85 mass % based on the mass of the copolymer, the content of the nitrile group-containing structural unit is 15 mass % or more and 50 mass % or less based on the mass of the copolymer, and the content of the substituted or unsubstituted carbamoyl group-containing structural unit is 10 mass % or less based on the mass of the copolymer. The weight-average molecular weight of the polymer is 5,000 or more and 400,000 or less.
