Abstract: The present disclosure provides a buffering member and a battery module, the buffering member comprises a first member and a second member. The first member comprises a first main body and a first connecting portion, the second member comprises a second main body and a second connecting portion. The first main body and the second main body face each other, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion. Because the first member and the second member are independent members, and they can be formed by separately cutting a sheet. Because the first member and the second member each are small in size and simple in structure, and they can be rapidly formed by using less material, the whole structure of the buffering member is simple and the buffering member uses less material, thereby maximally improving the utilization rate of the sheet.
