Zusammenfassung:	In an embodiment, a battery includes a container, a lid member, an electrode group, a current collecting tab, an electrode terminal, a lead and a spacer. The lid member is attached to a peripheral wall of the container with an opening of an inner cavity being closed. The current collecting tab protrudes in the electrode group in the inner cavity toward a side where the lid member is located, and the lead electrically connects the current collecting tab and the electrode terminal located in an outer surface of the lid member. The spacer is integrally formed of an electrically insulating material. The spacer includes a top plate portion sandwiched between the lead and the lid member, and a peripheral plate portion extending from the top plate portion toward a side where the electrode group is located and covering the lead and the current collecting tab in the inner cavity from an outer peripheral side.
