Abstract: Disclosed is a positive electrode composite in an all-solid battery. In particular, contents of the electrolyte, the positive electrode material, and the conductive material are non-linearly changed from the electrolyte layer toward the metal current collector. Accordingly, as being closer to the electrolyte layer, ion conductivity is increased, and as being closer to the metal current collector, electron conductivity is increased, such that the electrochemical reactions may be actively performed in the entire internal portion of the positive electrode composite.
