If the deficit of the solar neutrino (νe) flux is caused by the neutrino oscillation, there exists a lower bound of an effective neutrino flux detectable by electron scattering experiment, since the converted neutrino can also interact with atomic electron via neutral current effect. The effective reduction factor and day-night asymmetry for the 8B flux is calculated and plotted in the mixing parameter space, when matter oscillation effects both in the sun and in the earth are included, yielding a lower flux bound, ∼ 14% of the standard value.
