Abstract
An all-solid-state battery with which the occurrence of faults due to plating solution penetration can be further reduced and a non-defective item rate can be improved. An all-solid-state battery includes a laminated body in which electrode layers in which a current collector layer and active material layers are laminated with solid electrolyte layers containing a solid electrolyte there between. The electrode layer includes the current collector layer and the active material layers including an active material layer. The current collector layer includes a main body part formed inside the laminated body and an extension part that extends from an end surface from the main body part to an end surface of the laminated body. Then, the thickness (T) of the extension part on the end surface of the laminated body is smaller than the thickness (T) of the main body part.
