SOLID BATTERY AND BATTERY PACK USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a compact solid battery capable of preventing the occurrence of a current leakage between terminals of different batteries even in the case where dust is involved between a side face of a solid battery and a battery housing part of a compact electronic apparatus when the solid battery is housed in the housing part.SOLUTION: A solid battery 20 includes a protective layer 15 on the surface of a power storage element body having one or more power storage elements each of which includes a solid electrolyte layer 3 between a positive electrode layer 1 and a negative electrode layer 2. In at least a pair of facing surfaces of the solid battery 20, the ratio of the thickness at the central part of the solid battery 20 with respect to the thickness at an end part of the solid battery 20 is 0.65-0.95.
