Spontaneous CP violation is discussed in the standard six-quark model with several multiplets of Higgs fields. It is shown that the appearance of complex vacuum expectation values does not lead to a complex Cabibbo matrix, but generates CP violation in the interaction of Higgs bosons with quarks. Comparison of the theory with the experimental value of CP violation leads to the necessity of existence of light charged Higgs bosons, of the order of a few GeV in mass. Decays to these bosons should be the main decays for mesons containing heavy quarks. The model predicts a neutron dipole moment value approx.10/sup -25/ e-cm and for the decays of K mesons only a small deviation (approx.m/sup 2//sub ..pi..//m/sup 2//sub K/) from the predictions of the superweak model. The effects of CP violation in decays of D mesons are also estimated.
