<P>PROBLEM TO BE SOLVED: To provide a solid thin film battery in which quality is stabilized and its yield is improved by preventing breakage of a membrane of a solid electrolyte layer, and deterioration of battery performance can be prevented even in the case bending or the like is applied, and which has a high flexibility. <P>SOLUTION: This is the solid thin-film battery 1 which has a positive electrode layer 4, a negative electrode layer 6, a solid electrolyte layer 7 arranged between these layers, and a support body 2 on which these respective layers are laminated and supported, and is provided with chamfer parts 7, 7 at the side edge parts of the positive electrode layer or/and the negative electrode layer. By adopting this structure, breakage of a membrane of the solid electrolyte layer is prevented, and the solid thin-film battery with stable quality and high flexibility can be provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
