A nonaqueous electrolyte battery includes a flattened electrode group, a case, a positive electrode terminal and a negative electrode terminal. The positive electrode terminal is bent around one edge portion of the positive electrode terminal, curved toward the electrode group and reaches a sealed portion. The other edge portion of the positive electrode terminal extends from the case through the sealed portion. The negative electrode terminal is bent around one edge portion of the negative electrode terminal, curved toward the electrode group and reaches the sealed portion. The other edge portion of the negative electrode terminal extends from the case through the sealed portion. The positive electrode terminal satisfies formula (1) given below and the negative electrode terminal satisfies formula (2) given below: <?in-line-formulae description="In-line Formulae" end="lead"?>t<SUB>2</SUB>xW<SUB>2</SUB>>=0.25 S<SUB>p</SUB> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>t<SUB>3</SUB>xW<SUB>3</SUB>>=0.25 S<SUB>n</SUB> (2)<?in-line-formulae description="In-line Formulae" end="tail"?>
