The QCD non-perturbative property of effective locality whose essential meaning has been disclosed recently, is here questioned about the chiral symmetry breaking phenomenon, one of the two major issues of the non-perturbative phase of QCD. As a first attempt, quenching and the eikonal approximation are used so as to simplify calculations which are quite involved. Chiral symmetry breaking appears to be realised in close connection to the effective locality mass scale, μ~2, as could be expected.
