Zusammenfassung:	Provided are an electrode plate, including a current collector, an active substance layer, and a conductive structure. The current collector includes a body portion and a tab portion provided along a first direction, where the body portion is covered with the active substance layer, the tab portion is not covered with the active substance layer, and the conductive structure extends along the first direction and is connected to the tab portion, forming a connecting zone. In a second direction, the connecting zone has a dimension greater than thickness of a body region of the electrode plate, so that after an electrode assembly is wound, connecting zones of adjacent layers are mutually attached; where the second direction is a thickness direction of the electrode plate, the second direction is perpendicular to the first direction.
