Abstract
A cathode active material layer used for an all solid lithium battery, comprising a flat cathode active material with a hollowness in a range of more than 0% to 10%, and a solid electrolyte material, characterized in that the flat cathode active material has an aspect ratio (long axis length/short axis length) of 1.5 or more in a section in a thickness direction of the cathode active material layer, and a ratio of the flat cathode active material of which the short axis direction corresponds to a thickness direction of the cathode active material layer is 30% or more with respect to the whole cathode active material.
