Zusammenfassung:	To provide a secondary battery capable of improving the weld quality.SOLUTION: A secondary battery comprises: an electrode assembly: a collector plate bond to the electrode assembly; a case in which the electrode assembly is housed; a cap plate that is bonded to the case to seal the electrode assembly and the collector plate; and a terminal that is bonded to the collector plate and is penetrated through the cap plate to be exposed. In the secondary battery, a dual beam and a wobbling weld are conducted to at least one between the electrode assembly and the collector plate and between the collector plate and the terminal.SELECTED DRAWING: Figure 3b 【課題】本発明は溶接品質を高め得る二次電池を提供する。【解決手段】一例として、電極組立体；電極組立体に結合される集電板；電極組立体が収容されるケース；ケースに結合されて電極組立体および集電板を密封するキャッププレート；および集電板に連結されてキャッププレートを貫通して露出された端子を含み、電極組立体と集電板の間または集電板と端子の間のうち少なくとも一つにはデュアルビームおよびウォブリング溶接が遂行された二次電池が開示される。【選択図】図３ｂ
