This paper is devoted to a construction problem of unitary scattering matrix that arises in the case of nonlocal field theory. For Yukawa-like model, reformulated before in partially reduced field theory, the expression for S-matrix in the lowest (quadratic) coupling constant approximation is found. Unitarity of this operator is proved by direct calculation.
