The present invention provides a lithium secondary battery having: a positive electrode containing a positive electrode active material layer; and a negative electrode containing a negative electrode active material layer. The positive electrode active material layer and the negative electrode active material layer are disposed so as to face one another. The negative electrode active material layer has a region (A) containing a positive electrode non-facing part which does not face the positive electrode active material layer. The region (A) contains a negative electrode active material, a hot-melt binding material, and a temperature-sensitive thickening agent. The melting point of the hot-melt binding material and the gelatinization temperature of the temperature-sensitive thickening agent are both within the range of 45 to 100°C.
