<P>PROBLEM TO BE SOLVED: To provide an alkaline battery excelling in a load characteristic while keeping excellent electrolyte leakage resistance. <P>SOLUTION: A positive electrode part 2 is formed into a hollow cylindrical shape, and is structured such that a positive electrode pellet formed by molding a positive electrode mix into a hollow cylindrical shape is arranged inside a positive electrode can 1. Positive electrode mix density after molding the positive electrode mix before battery assemblage is 2.90-3.20 g/cm<SP>3</SP>; a moisture amount containing the positive electrode mix after the battery assemblage is 6.0-8.0 wt.% with respect to the weight of the positive electrode mix containing an electrolyte after the battery assembly; the average particle diameter of graphite is 10-50 μm; and apparent density of graphite is 0.01-0.05 g/cm<SP>3</SP>. <P>COPYRIGHT: (C)2008,JPO&INPIT |
