Abstract
A battery comprises a first polarity terminal that is attached via a first insulating member to an opening of an outer case. A first polarity plate includes: a first core formed of a conductive material; and a first active material layer. A first drawn-out portion is formed from a side of the first core on the first polarity terminal side thereof being drawn further out than a side of the first active material layer on the first polarity terminal side thereof. The first drawn-out portion includes a first bent portion that is bent towards the radially inner or outer side of the electrode body. A first surface of a first polarity collector plate contacts the surface of the first bent portion on the first polarity terminal side, and the first polarity terminal connects directly or via a conductive member to a second surface of the first polarity collector plate.
