1. An all-solid-state battery comprising 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 therebetween,
wherein the current collector layer is a single layer and includes a main body part formed inside the laminated body and an extension part that extends from an end surface of the main body part to an end surface of the laminated body,
wherein the thickness of the extension part on the end surface of the laminated body is smaller than the thickness of the main body part, and
wherein the thickness of the active material layers on the end surface of the laminated body is larger than the thickness of a region of the active material layers which overlaps the main body part.
