Zusammenfassung:	To provide a battery capable of maintaining an electrode lead surface covered with an insulating sheet unpeeled off even when the electrolyte adheres to the electrode lead.SOLUTION: A cylindrical battery in an embodiment includes an electrode body and a bottomed cylindrical outer can that houses the electrode body. The cylindrical battery further has a positive lead 12 connected to the electrode body and an insulating sheet 40 that covers the surface of the positive lead 12. A sheet base material constituting the insulating sheet 40 is connected directly to the surface of the positive lead 12.SELECTED DRAWING: Figure 4 【課題】電極リードに電解液が付着した場合でも、絶縁シートが剥離せず、電極リードの表面が絶縁シートに覆われた状態を維持できる電池を提供する。【解決手段】実施形態の一例である円筒形電池は、電極体と、電極体を収容する有底筒状の外装缶とを備える。円筒形電池は、さらに、電極体に接続された正極リード１２と、正極リード１２の表面を被覆する絶縁シート４０とを有する。絶縁シート４０を構成するシート基材は、正極リード１２の表面に直接接合している。【選択図】図４
