    Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery which reduces a flow space of an electrode assembly while securing an installation space of a lead tab.SOLUTION: A secondary battery according to one embodiment of the invention comprises: an electrode assembly; a case incorporating the electrode assembly; a cap assembly which is coupled to an opening of the case through a gasket and is connected to a plain part of the electrode assembly by a lead tab; and an electric insulating plate provided on the plain part. The gasket includes a support part which is supported by the electric insulating plate making a surface contact with the electric insulating plate. The support part forms an obtuse angle between at least one surface of an inner surface and outer surface when viewed in a first direction, and an upper surface of the electric insulating plate.
