An anode mixture layer that suppresses peeling from the anode current collector is provided. A positive electrode active material, a semi-solid electrolyte and a positive electrode binder, the positive electrode binder contains a fluorine-based resin, the content of the positive electrode binder in the positive electrode material mixture layer A, the value of the content of the positive electrode material in the positive electrode material mixture layer divided by the content of the positive electrode binder B In the case of, a positive electrode mixture layer satisfying 3.6 < 1.2 x 10 2 AB. |
