A battery (1) is provided with: a charge/discharge body (10) including electrodes (a positive electrode (11) and a negative electrode (12)) having electrode tabs (a positive electrode tab (11b) and a negative electrode tab (12b)); and a current collector (20) (a positive electrode current collector plate (21) and a negative electrode current collector plate (22)) joined to the electrode tabs (a positive electrode tab (11b) and a negative electrode tab (12b)). A current collector (20) (a positive electrode current collector plate (21) and a negative electrode current collector plate (22)) includes convex joining parts (a positive electrode joining part (21f) and a negative electrode joining part (22f)). Electrode tabs (a positive electrode tab 11b and a negative electrode tab 12b) are welded to joining parts (a positive electrode joining part 21f and a negative electrode joining part 22f). 电池1包括：包含具有电极耳片(正极耳片11b和负极耳片12b)的电极(正极11和负极12)的充放电体10；和与电极耳片(正极耳片11b和负极耳片12b)接合的集电体20(正极集电板21和负极集电板22)。集电体20(正极集电板21和负极集电板2
