Abstract

A solid battery including at least one first laminate body in which a first electrolyte layer, a first positive electrode layer, a first current collecting layer, and a second positive electrode layer are laminated in this order; at least one second laminate body in which a second electrolyte layer, a first negative electrode layer, a second current collecting layer, and a second negative electrode layer are laminated in this order; a first insulating layer connected to at least part of a side surface portion of the first laminate body; and a second insulating layer connected to at least part of a side surface portion of the second laminate body. Each of the first current collecting layer and the second current collecting layer has ionic conductivity of 10S/cm or lower, and each of the first insulating layer and the second insulating layer has ionic conductivity of 10S/cm or lower.
