The object of the invention is to provide a lithium secondary battery and method of manufacturing the same, wherein the lithium secondary battery can restrain the current collection property reduction in negative electrode (especially after primary charge and discharge), and improve the primary charge and discharge rate, discharge rate characteristic and circulation property. The lithium secondary battery contains a negative electrode binder containing a polyimide resin having a structure represented by the following chemical formula (1), and in the molecular weight distribution of the polyimide resin, the weight ratio of a polyimide resin having a molecular weight of less than 100,000 and a polyimide resin having a molecular weight from 100,000 to less than 200,000 is from 50:50 to 90:10.
