The disclosed manganese dry cell is provided with a hollow-cylindrical cathode mixture containing manganese dioxide; an anode can containing zinc; a separator disposed between the cathode mixture and the anode can; a cathode current collector inserted into the hollow portion of the cathode mixture; and an electrolyte. The cathode current collector contains a carbon rod and paraffin wax with which the carbon rod is impregnated. The carbon rod contains at least one element (A) selected from the group consisting of Fe, Cu, Ni, Co, Bi, and V; and the quantity of the element (A) contained in the cathode current collector is 0.1-4.0% by mass. The cathode current collector has a high deflective strength, low electrical resistance, and excellent reliability. |
