PROBLEM TO BE SOLVED: To enable coupling even when a manufacturing error is generated in reinforcement materials, to obtain a high reinforcement effect, in a case where a plurality of reinforcement materials are provided in a battery container. ! SOLUTION: A battery container 1 comprises a plurality of reinforcement materials 21 and 22, and a joint member 31 coupling between the reinforcement materials 21 and 22. The joint member 31 is provided with an insertion part coupled to the reinforcement materials 21 and 22. An air gap part is provided between the insertion part and the reinforcement material 21. !
