Microinstability of the mirror confined plasma (mean ion energy is 5∼10 keV and maximum density is 7×10^7 cm^<-3> under an rf electric field, ω_0=2.5ω_<ci> is investigated experimentally and theoretically, where ω_0 is the frequency of the rf field and ω_<ci> is the ion cyclotron frequency. The frequency of the observed oscillation, which is satisfactorily explained as a temporal growing loss cone instability, is above or nearly equal to 4ω_<ci>. It seems, as predicted by the calculation, to shift slightly from 4ω_<ci> by the effect of the rf field. This instability oscillation is damped with the rf field. The stabilization is owing to the energy spreading of ions and owing to the electron drifts induced by the rf field whose frequency is off-resonant from ion cyclotron frequency and its harmonics.
