Abstract
An all-solid-state rechargeable battery and a stacked all-solid-state rechargeable battery capable of reducing surface unevenness are provided. The battery makes it more difficult to crack a current collecting unit and to cut the current collecting unit, and the battery may be easily manufactured. The all-solid-state rechargeable battery includes positive and negative electrode layers; solid electrolyte layers stacked between the positive and negative electrode layers; an insulating layer on a side end surface of the positive electrode layer that covers the positive electrode layer; and thin type positive and negative electrode current collecting units protruding laterally from the positive and negative electrode layers, respectively. The insulating layer supports the positive and negative electrode current collecting units from at least one side. Two conductive units electrically connecting each of the positive and negative electrode current collecting units to an external wiring are formed in the insulating layer.
