Abstract

A cylindrical secondary battery comprises a current collector assembly that electrically connects the sealing cover with a core of one of the positive electrode plate and the negative electrode plate. The current collector assembly is composed of a combination of a current collector plate having a plate shape that is provided on an upper part of the electrode assembly and a current collector lead including a cylindrical part having opposed top and bottom parts and an axis along a main surface of the current collector plate, the top part is joined to a sealing plate that is a bottom surface of the sealing cover, and the bottom part is joined to the current collector plate The current collector lead further includes at least one rectangular tab part extending from an opening edge of the cylindrical part in a direction of the axis, and electrically connected with the current collector plate.
