Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method for a sealed battery having a superior volumetric efficiency and an excellent formability. SOLUTION: This manufacturing method for the sealed battery is provided with an inserting process to insert a group of electrodes 10 in an metallic outer can 2 having an opening part 20 formed at its upper end and having a bottom, a shrinking process to form a step part 30 between the opening part 20 and a barrel part 28 of the outer can 2 by shrinking the diameter of the barrel part 28 after the inserting process, and a calking process to apply calking between the opening part 20 and a sealing material 54 after disposing the sealing material 54 at the step part 30 after the diameter shrinking process.
