[SOLVING MEANS] An all-solid-state battery, wherein on a first side surface of an all-solid-state battery laminate, a first electrode current collector layer includes a first electrode current collector protruding part, which protrudes in a surface direction, and a second electrode current collector layer includes a second electrode current collector protruding part, which protrudes in a surface direction, a surface direction area of a second electrode-solid electrolyte laminate is larger than a surface direction area of a first electrode laminate, the first electrode laminate is laminated on the inside of the second electrode-solid electrolyte laminate when viewed from the lamination direction, and on the first side surface, an edge of the second electrode-solid electrolyte laminate in the surface direction is at least partially covered with a resin layer so that the first electrode current collector protruding part does not directly contact the edge in the surface direction of the second electrode-solid electrolyte laminate.
