Abstract: A lithium primary battery includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode contains a positive electrode material mixture including LixMnO2 where 0 ≤ x ≤ 0.05. The negative electrode contains at least one of metal lithium and a lithium alloy. The non-aqueous electrolyte contains an oxalate borate complex component and a cyclic imide component. In the non-aqueous electrolyte, the concentration of the oxalate borate complex component is 5.5 mass% or less, and the concentration of the cyclic imide component is 1 mass% or less. The mass ratio of the cyclic imide component to the oxalate borate complex component contained in the non-aqueous electrolyte is 0.02 or more and 10 or less.
