ELECTRICAL STORAGE DEVICE AND METHOD FOR MAKING THE SAME

To provide an electrical storage device in which a positive electrode material and a negative electrode material are each impregnated with a different type of electrolytic solution and a method for making the same. An electrical storage device () includes a negative electrode () including an organic electrolytic solution (), a positive electrode () including an aqueous electrolytic solution (), and a solid electrolyte () disposed between the negative electrode () and the positive electrode (). The negative electrode () is entirely sealed. The electrical storage device () includes a sealing member (), which is provided at the periphery of the negative electrode () and seals the negative electrode (). The solid electrolytes () form a pair including a sealing material and together with the sealing member () seal the negative electrode () so that the negative electrode () is disposed between the solid electrolytes ().
