Patent ID: 8034477

Claim:
A chip battery comprising: an element body including a solid electrolyte layer, a positive electrode layer provided on a surface of the solid electrolyte layer, and a negative electrode layer provided on another surface of the solid electrolyte layer; current collectors respectively provided on the positive electrode layer and the negative electrode layer of the element body; protective films arranged to cover a portion of a surface of each of the current collectors that extends perpendicular or substantially perpendicular to a lamination direction of the element body such that the surface of each of the current collectors that extends perpendicular or substantially perpendicular to the lamination direction of the element body includes an exposed portion that is not covered by the protective films; and terminal electrodes provided on end surfaces of the element body so as to contact a respective one of the current collectors along the exposed portion of the surface of the respective one of the current collectors that extends perpendicular or substantially perpendicular to the lamination direction of the element body.
