LITHIUM BATTERY AND METHOD FOR MANUFACTURING LITHIUM BATTERY

The purpose of the present invention is to efficiently manufacture a lithium battery having improved conductivity. Provided is a lithium battery including a substrate; a positive electrode material layer formed on one surface of the substrate; an electrolyte layer formed on the surface of the positive electrode material layer opposite to the surface facing the substrate; a buffer layer formed on the surface of the electrolyte layer opposite to the surface facing the substrate; a negative electrode layer containing lithium, which is formed on the surface of the buffer layer opposite to the surface facing the substrate. The electrolyte layer has a recessed part that is recessed toward the substrate in a portion of the surface facing the negative electrode layer, and the buffer layer is formed such that the buffer layer fills the recessed part.
