  Supersymmetric models with spontaneous supersymmetry breaking suffer from the
notorious sign problem in stochastic approaches. By contrast, the tensor
network approaches do not have such a problem since they are based on
deterministic procedures. In this work, we present a tensor network formulation
of the two-dimensional lattice $\mathcal{N}=1$ Wess-Zumino model while showing
that numerical results agree with the exact solutions for the free case.
