We discuss the CP violation based on the SU(2)×U(1)×SU_F(2) gauge model, where the new gauge bosons S^i_μ are introduced in association with the extra subgroup SU_F(2). The effective coupling constant G_S for the interaction mediated by the S^i_μ is found to be G_S/G_F > 5×10^<-6>. In this model the gauge bosons S^i_μ are coupled to off-diagonal neutral currents. The ratio R=[Γ(K^±→π^±eμ^^-)+Γ(K^±→π^±μe^^-)]/Γ(K^-→π^0μν^^-_μ) is predicted to be R>2×10^<-9>.
