ABSTRACT:
A chip battery includes an element body including a solid electrolyte layer, a positive electrode layer, and a negative electrode layer. Current collectors are provided on the positive electrode layer and the negative electrode layer, respectively, of the element body using a conductive material, such as Pt. In addition, protective films are provided on both end surfaces of the element body and on the current collectors so that the current collectors are exposed near the respective ends in the longitudinal direction of the element body. Further, protective films are provided on the side surfaces of the element body to define a base body. Further, terminal electrodes are provided on the base body so as to be brought into surface contact with the exposed surfaces of the current collectors on both end sides in a direction substantially perpendicular to the lamination direction of the element body.
