  To elucidate the pseudogap phase diagram including the overdoped state of
high transition temperature (high-$T_c$) cuprates, we must understand the
origin of the positive out-of-plane magnetoconductivity (MC) observed in these
compounds. For this purpose, the out-of-plane resistivity $\rho_c(T,H)$ of an
overdoped Bi$_{1.6}$Pb$_{0.4}$Sr$_{2}$CaCu$_{1.96}$Fe$_{0.04}$O$_{8+\delta}$
(Bi-2212) single crystal is measured under pulsed magnetic fields up to 60 T.
We show that the superconductive density-of-states (DOS) depletion effect, in
addition to the pseudogap effect, clearly appears below the superconductive
fluctuation regime, and the contribution becomes dominant in the
superconducting state.
