Abstract

Provided is a nonaqueous electrolyte secondary battery including a bottomed cylindrical positive electrode casing and a negative electrode casing which is fixed to an opening of the positive electrode casing through a gasket. The opening of the positive electrode casing is caulked to the negative electrode casing side to seal the accommodation space. A shortest distance Lbetween a caulking tip end and the negative electrode casing in the opening of the positive electrode casing is equal to or less than 70% of an average sheet thickness of the positive electrode casing, a shortest distance Lbetween a tip end of the negative electrode casing and the positive electrode casing is equal to or less than 60% of the average sheet thickness of the positive electrode casing, and a distance Lbetween the tip end of the negative electrode casing and the bottom of the positive electrode casing is equal to or less than 110% of the average sheet thickness of the positive electrode casing.
