    摘要： A cylindrical lithium secondary battery includes an electrode assembly which has a first electrode plate, a second electrode plate, and a separator provided between the first electrode plate and the second electrode plate, is wound in a spiral shape, and has a central space at the center of winding; a core member which is inserted into the central space of the electrode assembly; a case having a space for containing the electrode assembly; and a cap assembly which is connected to an upper portion of the case so as to seal the case. The core member is formed in a tube shape having a gap along a longitudinal direction, which divides the core member into a body portion and left and right lateral end portions, wherein an imaginary arc line extending from an outer circumferential surface of the body portion of the core member defines an imaginary circumference, and wherein the left and right lateral end portions are located inside the imaginary circumference and comprise a pair of first bending portions, inwardly bending and symmetrically disposed with respect to the gap, and a pair of second bending portions bending in a rotation direction that is opposite to the inwardly bending rotational directions of the first bending portions.
