The present invention provides a high-purity arylsulfonic acid amine salt vinyl monomer which is an extremely industrially useful arylsulfonic acid monomer with excellent storage stability and amphiphilic solubility in both water and organic solvents, a simple and practical method for producing the same, a polyarylsulfonic acid amine salt which is a polymer thereof, and a method for producing the same. In the arylsulfonic acid amine salt vinyl monomer, a tertiary amine having 2 or 3 different substituents that each have 1 to 7 carbon atoms and also containing at least one or more of tertiary carbon or quaternary carbon or cyclic skeleton in the structure is applied to an amine moiety thereof, and in addition, a polyarylsulfonic acid amine salt having high purity in terms of sulfonation rate and polymerization conversion rate and a polymer thereof are used.
