  "textContent": "A positive electrode 2 and a negative electrode 3 are contained in a battery case 1 with a separator 4 interposed therebetween. The positive electrode 2 contains manganese dioxide and an alkaline electrolyte, and the negative electrode 3 is a gelled negative electrode containing zinc powder, a gelling agent, and an alkaline electrolyte. The zinc powder contains 15 % by mass or higher of fine powder with a particle size smaller than 200 mesh, and 10 to 35 % by mass of coarse powder with a particle size of 20 to 80 mesh, and has a specific surface area in the range of 0.025 to 0.080 m 2 /g.",
