The stress-energy tensors are computed for scalar and spinor fields with arbitrary mass in anti-de Sitter spacetime using the ζ-function technique. The results are compared with those obtained by Pauli-Villars regularization. It is found that they agree with one another. The trace anomaly for the Wess-Zumino model (the scalar supermultiplet) in anti-de Sitter spacetime is studied. It is concluded that the trace anomaly must take the ``conventional'' value in this model although the physical significance of the stress-energy tensor is not clear in anti-de Sitter spacetime. The relation between the ζ-function and Pauli-Villars methods in an arbitrary space is also clarified.
