The structure of the symmetry algebras of normal \(A\)-hypergeometric systems is studied here by using the theory of \(b\)-functions. A structure theorem of symmetry algebras of normal \(A\)-hypergeometric systems in terms of generators and relations is found. For a definition of \(A\)-hypergeometric systems refer to \textit{I. M. Gel'fand, M. I. Graev} and \textit{A. V. Zelevinski} [Dokl. Akad. Nauk SSSR 295, 14-19 (1987; Zbl 0661.22005)].
