Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a square secondary battery having high productivity and reliability.SOLUTION: A secondary battery includes: a power storage element having a positive electrode tab group consisting of a plurality of positive electrode tabs protruding from the end of one side and a negative electrode group consisting of a plurality of negative electrode tabs; a positive electrode lead connected to the positive electrode tab group; and a negative electrode lead connected to the negative electrode group. The positive electrode tab group and the negative electrode tab group are separated from each other and arranged, the positive electrode tab group is sandwiched by the positive electrode lead and the negative tab group is sandwiched by the negative electrode lead.SELECTED DRAWING: Figure 4 【課題】生産性や信頼性の高い角形二次電池を得ること。【解決手段】本発明の二次電池は、一方側の端部から突出した複数の正極タブからなる正極タブ群及び複数の負極タブからなる負極タブ群を有する蓄電要素と、正極タブ群に接続される正極リード及び負極タブ群に接続される負極リードと、を備え、正極タブ群と負極タブ群とはそれぞれ分離して配置され、正極タブ群は正極リードで挟持され、負極タブ群は負極リードで挟持される。【選択図】図４
