In this paper, we determine (tau q) over tilde (X-q(lambda)), the Gauss sums on the Iwahori-Hecke algebras of type A for irreducible characters X-q(lambda), which are q-analogues of those on the symmetric groups. We also explicitly determine the values of the corresponding trace function Psi((n))(q) = Sigma(lambda 1-n) (tau(q)) over tilde (X-q(lambda))X-q(lambda).

We shall discuss Gauss sums on finite groups and give several examples including the case of the complex reflection groups G(m, r, n), and hence finite symmetric groups, and also finite Weyl groups.
