Abstract: Electrochemical device 200 disclosed includes positive electrode 10 and negative electrode 20. Positive electrode 10 includes a positive electrode material layer. The positive electrode material layer contains particles of an active material and a conductive agent. The cohesive force between the particles of the active material and the conductive agent is greater than the cohesive force between the conductive agent.
