Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a friction stir welding method reduced in a load on a battery body.SOLUTION: The present invention provides a friction stir welding method for joining an electrode terminal 12 of a battery and a bus bar 20 using a joining tool 30 for friction stir welding. Such a friction stir welding method includes the steps of: forming a recess 21 to the bus bar 20; and overlapping the electrode terminal 12 and the bus bar 20 to press the joining tool 30 to the recess 21 of the bus bar 20.SELECTED DRAWING: Figure 2 【課題】電池本体への負荷が軽減された摩擦攪拌接合方法を提供する。【解決手段】本発明により、摩擦撹拌接合用の接合ツール３０を用いて、電池の電極端子１２とバスバー２０とを接合する摩擦撹拌接合方法が提供される。かかる摩擦撹拌接合方法は、バスバー２０に凹状部２１を形成する工程と、電極端子１２とバスバー２０とを重ねて、バスバー２０の凹状部２１に接合ツール３０を押し付ける工程と、を包含する。【選択図】図２
