PROBLEM TO BE SOLVED: To improve deflection strength of a carbon rod used as a positive electrode collector of a manganese dry cell and to improve liquid-leakage resistance characteristics by suppressing the permeability of an electrolyte when the carbon rod is used in the manganese dry cell.SOLUTION: There is provided a manganese dry cell having excellent liquid-leakage resistance characteristics by suppressing permeation of an electrolyte in which a dense carbon rod which is suppressed in the occurrence of cracks during baking is obtained by eliminating nonuniformity during mixing by mixing and baking a carbonaceous powder and clay and the carbon rod is used in the manganese dry cell. |
