ABSTRACT:
An all-solid-state lithium secondary cell has a laminate, and a pair of external current collectors. The laminate is shaped into substantially a rectangular parallelepiped and is made of a positive electrode, a negative electrode, and a solid electrolyte between the positive and negative electrodes. The external current collectors are disposed at both ends of the laminate to support side faces of the laminate. One of the current collectors is connected to the positive electrode and the other to the negative electrode. A chamfered shape or an R-chamfered shape is provided at the edges and along the ridges of the laminate.
