For a polynomial p on C~n, the variety V_p = {z ∈ C~n;p(z) = 0} will be considered. Let Exp(V_p) be the space of entire functions of exponential type on V_p, and Exp'(V_p) its dual space. We denote by (partial deriv)_p the differential operator obtained by replacing each variable z_j with partial deriv/partial deriv z_j in p, and by O partial deriv_p(C~n) the space of holomorphic solutions with respect to partial deriv_p. When p is a reduced polynomial, we shall prove that the Fourier-Borel transformation yields a topological linear isomorphism: Exp'(V_p) → O partial deriv_p(C~n). The result has been shown by Morimoto, Wada and Fujita only for the case p(z) = z_1~2 +… + z_n~2 + λ (n ≥ 2).
