PURPOSE:To provide a battery which is easy to manufacture, having a stable and constant characteristic by filling the required powder substance between electrodes and between electrode groups, and then covering the top of the powder substance with a foamed continuous plastic foam. CONSTITUTION:A granular powder substance 13 of high flowability forming a coarse secondary particle of very fine primary particles coagulated is filled as an electrolytic solution holding member in the space between a positive electrode plate 1 and a negative electrode plate 2 and between electrode body groups which are separated with a separator 3. The upper surface of powder substance 13 is covered with a formed acid-resistant continuous plastic foam 12. A fixed amount of the powder substance in which a fixed amount of the electrolytic solution is injected with the expansion caused at the time of foaming, is sealed in the case where the filled space is different, thereby making a sealed lead-acid battery which is easy to manufacture, having a stable and constant characteristic. |
