Abstract:
1. A solid electrolyte battery comprising: a positive electrode; a negative electrode disposed opposite to said positive electrode; a separator disposed between said positive electrode and said negative electrode; and solid electrolytes each of which is disposed between said positive electrode and said separator and between said separator and said negative electrode; wherein said separator is formed by bonding a first separator constituted by polyethylene and a second separator constituted by polypropylene to each other, said separator has a thickness satisfying a range not less than 5 μm nor greater than 15 μm and said separator has a shutdown temperature which is substantially the same as the shutdown temperature of a separator constituted by polyethylene and a meltdown temperature which is substantially the same as the meltdown temperature of a separator constituted by polypropylene.
