PROBLEM TO BE SOLVED: To provide a sealed battery improved in energy density per volume. SOLUTION: In the manufacturing method of the sealed battery, where a positive electrode tab 5 or a negative electrode tab 4 for conductive connection jointed to a battery element is jointed to an inner wall surface of a battery can 2, the tab for conductive connection jointed to the battery element 3 and a junction 7 of the inner wall surface of the battery can is jointed in a state extending outside from the opening of the battery can, a portion extending from the junction to a side opposite to the battery element is bent, in a direction opposite of a battery wall surface of the junction, and the battery is sealed by attaching a battery header 9. |
