In this paper, we introduce a new method of producing functional relations among multiple zeta-functions. This method can be regarded as a kind of multiple analogue of Hardy's one of proving the functional equation for the Riemann zeta-function. Using this method, we give new functional relations for multiple zeta-functions. In particular, substituting positive integers into variables of them, we obtain known relation formulas for the multiple zeta-values. Furthermore, applying our method to a certain series involving hyperbolic sine functions, we can obtain certain multiple analogues of the known results given by Cauchy, Ramanujan, Berndt and so on.
