The contribution of the proton electric dipole moment was obtained via core polarization effects that were treated in the framework of random phase approximation with effective residual forces. We derived a new upper bound $|d_p|< 5.4\times 10^{-24} e\cdot$cm of the proton electric dipole moment.4 pages, 2 figures, RevTex4Nuclear TheorySchiff moment of the Mercury nucleus and the proton dipole momenttext
