Provided is a solid-state battery with improved battery characteristics and reliability. The solid-state battery of the present technology includes: at least one first laminate formed by laminating a first electrolyte layer, a first positive electrode layer, a first collector layer, and a second positive electrode layer in this order; and at least one second laminate formed by laminating in this order A second electrolyte layer, a first negative electrode layer, a second collector layer, and a second negative electrode layer; a first insulating layer connected to at least a part of the side surface of the first laminate; and a second insulating layer connected to On at least a part of the side surface of the second laminate, the first laminate and the second laminate are composed of a main plane of the first electrolyte layer on which the first positive electrode layer is not laminated, and the second negative electrode layer on which the second collector layer is not laminated. The main plane is laminated, or the main plane of the second electrolyte layer without the first negative electrode layer is laminated, and the main plane of the second positive electrode layer without the first collector layer is laminated. The first collector layer and The respective ionic conductivity of the second collector layer is 10-7 S/cm or less, and the respective ionic conductivity of the first insulating layer and the second insulating layer is 10-7 S/cm or less. |
