  "textContent": "A lithium primary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes a positive electrode mixture. The positive electrode mixture contains manganese dioxide and an oxide of a metal Me. The metal Me has a valence of 2 or more, an ionic radius of 0.8 Å or less, and an electronegativity of 1.65 or less. The amount of the oxide of the metal Me contained in the positive electrode mixture is 0.1 parts by mass or more and 5 parts by mass or less relative to 100 parts by mass of the manganese dioxide contained in the positive electrode mixture. The negative electrode includes an alloy containing lithium and magnesium. The content of the lithium in the alloy is greater than 88% by mass. The content of the magnesium in the alloy is 0.01% by mass or more and 10% by mass or less.",
