摘要： The present invention provides a bipolar battery made by using a polymer gel electrolyte or a liquid electrolyte in an electrolyte layer, which is highly reliable and prevents liquid junction (short circuit) caused by leak out of an electrolyte solution from the electrolyte part. The present invention provides a bipolar battery laminated, in series, with a plurality pieces of bipolar electrodes which is formed with a positive electrode on one surface of a collector, and a negative electrode on the other surface, so as to sandwich an electrolyte layer, characterized by being provided with a separator which retains the electrolyte later, and a seal resin which is formed and arranged at the outer circumference part of a part of the separator where the electrolyte is retained.
