PROBLEM TO BE SOLVED: To suppress rising of internal resistance during storage while keeping excellent low temperature discharge characteristics in a nonaqueous electrolyte primary battery composed of a positive electrode using manganese dioxide as the main active material, a negative electrode comprising lithium or a lithium alloy, and an electrolyte. SOLUTION: In the nonaqueous electrolyte primary battery containing a positive electrode 1 using manganese dioxide as the main active material, a negative electrode 2 containing metallic lithium or a lithium alloy, and a nonaqueous electrolyte containing a solvent and an electrolyte salt, divinyl sulfone and dimethyl phthalate are added to the nonaqueous electrolyte.
