Electrodeposition of lead peroxide on the graphite core was studied. The results are following; 1) At more noble potential than 1.6V vs. S.C.E. and lower temperature than $40^{\circ}C$, $PbO_2$ deposited current efficiency is increased but deposited layer falls off easily from graphite core. 2) Oxygen overvoltage of $PbO_2$ deposited layer on the graphite core is largely with increasing $PbO_2$ depositing anodic potential and with lowlying electrolytic temperature. 3) To obtain the $PbO_2$ deposited layer without falling off from the graphite core, it is necessary to change the electrolytic conditions, anodic potential and electrolytic temperature, in four stages successively.
