Abstract
An electrode for a battery in which a collector and an electrode tab are connected with a novel connection structure without impairing electrical connection, and a method of manufacturing the electrode quite simply are provided. Further, a battery having this electrode for the battery is provided. A collector (2) and a tab (3) are connected via a graphite layer (4). The graphite layer is formed on the surface of the collector to be connected with the tab and/or the surface of the tab to be connected with the collector, the portions to be connected of the collector and the tab are overlapped on each other with the graphite layer interposed between the collector and the tab, and a pressure is applied to the overlapped portions to connect the collector (2) with the tab (3). It is preferable that the collector (2) is made of a conductive thin film formed on a resin film (5).
