Abstract

A lithium secondary battery includes: an internal electrode body including a positive electrode, a negative electrode, and a separator, the positive electrode and the negative electrode being wound via the separator so that the positive electrode and the negative electrode are not brought into direct contact with each other, and an organic electrolyte. An average current collecting area obtained by dividing a positive electrode area (cm.sup.2) by the number of current-collecting tabs to be attached to the positive and negative electrodes is 360 or less.
