Problems solved by technology

[0016] Incidentally, in the case of the conventional battery module 10, as described above, the heat transfer path is complicated, so it is difficult to efficiently transfer the heat generated from the battery cells 11
The module frame 30 itself may degrade heat transfer characteristics, and a fine air layer such as an air gap that may be formed between the module frame 30, the heat transfer member 50, and the heat sink 60, respectively, may also be a factor deteriorating the heat transfer characteristics.
