A soluble example in field theory with Fermi interaction is proposed. The two fermion fields N and N are interacting as N + N \rightleftarrowsN + N. It is shown that the limit of Machida's soluble model in which the probability amplitude for a bare meson identically vanishes coincides with our model with the separable form factors.
This model with general form factors and another model are discussed.
