<P>PROBLEM TO BE SOLVED: To provide a manganese dry cell having excellent discharge performance. <P>SOLUTION: A positive electrode mixture 1 is contained in a bottomed cylindrical negative electrode zinc can 4 via a separator 3, a carbon rod 2 pressure inserted in the vicinity of the center of the positive electrode mixture 1 is fitted to the inside of a substantially columnar protrusion of a positive electrode terminal 11 and brought into electrical contact therewith. Since an n-regular prismatic carbon rod 2 is employed in such a manganese dry cell, occupied area of the carbon rod in the cell can be reduced as compared with that of a conventional columnar carbon rod, and thereby more active material can be filled correspondingly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
