This invention relates to a method of producing a plate for a lead storage battery which comprises packing into an active material support a paste prepared by kneading a lead oxide having a minium content of up to 90 % or a mixture of this lead oxide powder with lead power with water and sulfuric acid as the principal components. Since the lead oxide powder having a minium content of up to 90 % is used, minium on the surface of this oxide and lead oxide in the particle core are directly bonded and bonding power between the active materials when kneading the paste is enhanced. The plate prepared by this method provides high adhesion of the paste to the active material support and high bonding power between the active materials. Therefore, the formation charge efficiency can be improved by minium and the service life when used in a battery can be improved.
