  "textContent": "Disclosed is an alkaline primary battery including: a bottomed cylindrical battery case; a cylindrical positive electrode having a hollow, being in contact with an inner wall of the battery case, and including manganese dioxide; a gel negative electrode being in the hollow of the positive electrode, and including zinc or a zinc alloy; a separator interposed between the positive electrode and the negative electrode; and an alkaline electrolyte. The positive electrode has an electric capacity C1 and a height L1, the negative electrode has an electric capacity C2 and a height L2, the electric capacity C1 and the electric capacity C2 satisfy the relational expression (1): 1.05 ¤ C ¢ 2 / C ¢ 1 ¤ 1.25 and the height L1 and the height L2 satisfy the relational expression (2): 0.85 ¤ L ¢ 2 / L ¢ 1 ¤ f C ¢ 2 / C ¢ 1 where f C ¢ 2 / C ¢ 1 = - 0.3058 × C ¢ 2 / C ¢ 1 + 1.3153.",
