摘要： An alkaline battery of this invention includes: a positive electrode including at least one selected from the group consisting of a manganese dioxide powder and a nickel oxyhydroxide powder; a gelled negative electrode including a zinc alloy powder, a gelling agent, and an alkaline electrolyte; and a separator interposed between the positive electrode and the gelled negative electrode. The gelling agent comprises a polymer that is obtained by polymerizing a polymerizable monomer including at least an acrylic monomer, and part of the acrylic monomer remains in the gelling agent without being polymerized. The acrylic monomer includes at least one selected from the group consisting of acrylic acid, methacrylic acid, an acrylate, and a methacrylate. The weight ratio of the remaining acrylic monomer to the total weight of the polymer and the remaining acrylic monomer is 5000 ppm or less.
