<P>PROBLEM TO BE SOLVED: To provide a comparatively thin and small water battery that is an improvement of conventional water batteries, and that can generate a predetermined electromotive force with a slight amount of water supply. <P>SOLUTION: A layer of positive electrode active material 14 abutting on an inside face of the positive electrode plate 12 intervenes between an positive electrode plate 12 and a negative electrode plate 13 intervenes. An electricity insulator layer intervenes between the positive electrode plate 12 and an inside face of the negative electrode plate 13. Outer surfaces of both positive electrode plate 12 and negative electrode plate 13 are enclosed with an external enclosure sheet 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
