A simple mechanism for SUSY breaking is proposed due to the coexistence of BPS domain walls. It requires no messenger fields nor complicated SUSY breaking sector on any of the walls. We assumed that our world is on a BPS domain wall and that the other BPS wall breaks the SUSY preserved by our wall. We obtain an \cal N=1 model in four dimensions which admits an exact solution of a stable non-BPS configuration of two walls. The stability is assured by a topological quantum number associated with the winding on the field space of the topology of S1. We propose that the overlap of the wave functions of the Nambu-Goldstone fermion and those of physical fields provides a practical method to evaluate SUSY breaking mass splitting on our wall thanks to a low-energy theorem. This is based on our recent works hep-th/0009023 and hep-th/0107204.
