Solid-state battery and method of manufacturing solid-state battery

A solid-state battery comprising:

• a laminate in which a negative electrode current collector layer, a negative electrode active material layer, a solid electrolyte layer, a positive electrode active material layer, and a positive electrode current collector layer are laminated in this order in a laminating direction,
• the negative electrode active material layer comprising at least one of lithium metal or a lithium alloy, wherein
• an intermediate layer is optionally laminated between the negative electrode active material layer and the solid electrolyte layer,
• the negative electrode active material layer has a lamination surface covered with the solid electrolyte layer or the intermediate layer,
• the negative electrode active material layer has an outer edge extending in directions orthogonal to the laminating direction of the laminate and covered with a first insulating member,
• the positive electrode active material layer has an outer edge extending in the directions orthogonal to the laminating direction of the laminate and covered with a second insulating member,
• in each of the directions orthogonal to the laminating direction, a length obtained by subtracting a length from a center of the laminate to an outer end of the first insulating member from a length from the center of the laminate to an outer end of the second insulating member is defined as c, and c is larger than 0 (c>0).
