To provide a battery pack capable of taking out battery cells by disassembling the battery pack easily for recycling the battery cells in a battery pack using plural high-capacity lithium secondary battery cells. The battery cells are fixed by a cell holder and are housed inside a case in a state where both electrodes are sandwiched by a positive-electrode current collecting plate and a negative-electrode current collecting plate, and springs are arranged above and under the plates. There are claws on side surfaces of the case, which can temporarily fix the springs to the current collecting plates at the time of assembly and prevents the case from being ejected suddenly when a fastener is released at the time of disassembly, as a result, assembly/disassembly can be easily performed. |
