(57) [Problem] To provide a primary battery having high voltage, high capacity, and low self-discharge. SOLUTION: A positive electrode comprising a positive electrode current collector 4 and a positive electrode mixture 3, a negative electrode 1 containing aluminum or an aluminum alloy, and an electrolytic solution 2 sandwiched between the positive electrode and the negative electrode 1 are provided. At least one ion selected from the group consisting of (SO 4 2− ) and nitrate ion (NO 3 − ) is used, and in the electrolytic solution 2, nitrogen-containing organic substances and salts, esters, anhydrides, and ions thereof are used. A battery using aluminum as a negative electrode, comprising using an electrolytic solution 2 containing at least one selected from the group consisting of: |
