Abstract:
A solid-electrolyte battery comprising:an elongated positive electrode having lengthwise and widthwise directions and a lengthwise end; a positive-electrode lead formed into substantially a rectangular shape having a long side and a short side connected to said positive electrode such that the long side of said positive-electrode lead is substantially in parallel with the widthwise direction of said positive electrode; an elongated negative electrode having lengthwise and widthwise directions disposed opposite to said positive electrode; a negative-electrode lead formed into substantially a rectangular shape having a long side and a short side connected to said negative electrode such that the long side of said negative-electrode lead is substantially in parallel with the widthwise direction of said negative electrode; and a solid electrolyte layer formed on at least either surface of said positive electrode and said negative electrode, wherein said positive electrode and said negative electrode are laminated such that the surfaces in each of which said solid electrolyte layer is formed are disposed opposite to each other and wound in the lengthwise direction so as to be accommodated in a case of said solid-electrolyte battery, and the short side of at least either of said positive-electrode lead or said negative-electrode lead which is connected to said positive electrode or said negative electrode such that said short side is disposed opposite to the lengthwise end of said positive electrode or said negative electrode is shifted inwards as compared with the lengthwise end of said positive electrode or said negative electrode.
