PURPOSE:To obtain a manganese dry cell excellent in the properties of squeeze processing and corrosion resistance by using high chrome steel, which does not contain Ni but contains a specific quantity of Cr, for a can used for both a collector of a positive pole and a negative pole and collection of electricity. CONSTITUTION:A positive pole 1, which is added by carbon black as a conductive material having MnO2 as the main acting substance as well as molded by pressure while being added by a binder, is inserted into a positive can 2 in a state of directly making contact with the can. Said positive can 2 is formed by high Cr steel, which contains no Ni but not less than 25wt% of Cr. Further a Zn plate 3 of a negative pole is stored directly making contact with a negative can 4, wherein high Cr steel is used like the positive can. Thereby a battery excellent in corrosion resistance can be obtained at a low cost. |
