Abstract: There is provided a battery buffering member that has heat insulating performance by including heat insulating members, and the heat insulating performance is hardly deteriorated even when the buffering member is compressed under an external force in a thickness direction thereof. The battery buffering member comprises an elastic member having protruding portions, and heat insulating members that are plate-like structures having through-holes formed thereon, wherein the heat insulating members are disposed on one surface side and the other surface side of the elastic member, respectively, and the protruding portions of the elastic member protrude from the through-holes of the heat insulating members.
