Alkaline dry battery

An alkaline dry battery comprising:

• a cylindrical positive electrode mixture having a hollow and including at least one of manganese dioxide powder and nickel oxyhydroxide powder;
• a gelled negative electrode filled in the hollow of said positive electrode mixture, said gelled negative electrode including zinc alloy powder;
• a separator interposed between said positive electrode mixture and said gelled negative electrode;
• a negative electrode current collector having a rod-like body inserted into said gelled negative electrode and a head at one end of said body;
• and
• a negative electrode terminal plate electrically connected to the head of said negative electrode current collector,
• wherein said alkaline dry battery is a AA-size alkaline dry battery, and
• the body of said negative electrode current collector is in the shape of a column with a diameter of 1.0 to 1.3 mm, and
• the height L1 of said gelled negative electrode filled in the hollow of said positive electrode mixture and the length L2 of the portion of said negative electrode current collector inserted in said gelled negative electrode satisfy the relation (3):
• 0.72≦L2/L1≦0.86.
