    • PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte solution battery with high safety by forming terminal structure capable of preventing or restraining a spark which may be generated in a terminal portion caused by leakage of nonaqueous electrolyte solution.
      SOLUTION: The nonaqueous electrolyte solution battery 1 which has a structure having a battery case 20 made from metal, outer terminals 30b, 40b insulated therefrom, and fix member 32, 33, 42 and 43 fixing the outer terminals is so constituted that the outer terminal 30b existing in at least positive side is formed from aluminum alloy material and its fix member 32, 33 is formed from aluminum alloy material or electrical insulating material. Even if the nonaqueous electrolyte solution leaks in its portion B to form a bridge, an active radical promoted by the ionization of transition metal is less generated and an organic catalyst is restrained to dissociate, and thus the spark is prevented or restrained.
