The present invention relates to a lithium primary battery using lithium metal or an alloy thereof as a negative electrode active material, and more particularly to a lithium primary battery excellent in discharge characteristics at low temperatures. In a lithium primary battery comprising a negative electrode containing lithium metal or a lithium alloy as a negative electrode active material, a positive electrode, and a non-aqueous electrolyte, as a solvent for the non-aqueous electrolyte, Formula R 1 —COO—R 2 (Wherein R 1 is C m H 2m + 1 , R 2 is C n H 2n + 1 , 4 ≦ m + n, 1 ≦ m ≦ 3 and 1 ≦ n ≦ 5) It contains the chain ester represented by these.
