A core structure for a cylindrical lithium secondary battery is provided to overcome a dimensional error occurring in a core or case by deformation of a connection member, and thus enable a successful assembling of a battery. A core structure for a cylindrical lithium secondary battery is disposed within a case(20) of a battery, and includes a core(30), an electrode assembly(40), and two conductive fixing assemblies(50). A connection member(60) acts as an electric linking part to connect conductive pressing pieces(52) to a positive electrode lead terminal(21) or negative electrode lead terminal(22). The connection member is a curved flexible structure. |
