description	To provide a battery with low risk of breakage of tabs and tab recognition errors.SOLUTION: A battery comprises a wound electrode body formed from a band-shaped first electrode 22 and a band-shaped second electrode to be joined to each other via a band-shaped separator and wound. The first electrode 22 has a first tab 27 and second tabs 28A, 28B, 28C projecting in a projection direction PD. A width W1 (mm) of the first tab 27 at a distance L (3 to 10 mm) in the projection direction PD, a width W2 (mm) of the second tab 28A at the distance L in the projection direction PD, and a width W3 (mm) of the first tab 27 at its root satisfy both of the following relational expressions of (W3/W1)>1.5 and (W2/W1)>1.2.SELECTED DRAWING: Figure 8 【課題】タブ折れやタブ認識不良の発生が抑制された電池を提供する。【解決手段】ここで開示される電池は、帯状の第１電極２２と、帯状の第２電極とが、帯状のセパレータを介して積層され、捲回されてなる捲回電極体を備える。第１電極２２は、突出方向ＰＤに突出した第１タブ２７と第２タブ２８Ａ～２８Ｃとを有し、第１タブ２７の突出方向ＰＤに距離Ｌ（ただし、Ｌ＝３～１０ｍｍ）の位置における幅をＷ１（ｍｍ）とし、第２タブ２８Ａの突出方向ＰＤに距離Ｌの位置における幅をＷ２（ｍｍ）とし、第１タブ２７の根元の幅をＷ３（ｍｍ）としたときに、次の関係式：（Ｗ３／Ｗ１）＞１．５；（Ｗ２／Ｗ１）＞１．２；をいずれも満たす。【選択図】図８
