A battery device includes: a plurality of battery cells, each including a cell case provided with a relief valve that opens when internal pressure reaches a predetermined threshold; a case that houses the plurality of battery cells; a non-combustible paper that is provided at at least a part of an inner surface of the case; an intermediate material that is provided at a surface of the non-combustible paper opposite from the inner surface and that has a higher mechanical strength than the non-combustible paper; and an insulating plate that is provided at a surface of the intermediate material opposite from the non-combustible paper, that opposes the relief valves, and that has electrical insulation properties and a higher mechanical strength than the non-combustible paper, wherein thermal insulation properties of the non-combustible paper and the intermediate material are higher than those of the insulating plate.
