<p>PROBLEM TO BE SOLVED: To provide a battery module that can be miniaturized and reduced in weight while heat radiation of a battery call is enhanced.SOLUTION: A battery module has plural battery cell 10 arrays each comprising plural cylindrical battery cells 10 which are linearly arranged in the radial direction thereof, a first spacer 21 disposed between the plural battery cell 10 arrays, and plural first leads 22 which are electrically connected to one electrodes of the plural cylindrical battery cells 10. The plural battery cell 10 arrays are arranged to be stacked in the perpendicular direction to the battery cell 10 arrays, the first spacer 21 is formed of metal material, and the plural first leads 22 are respectively connected to the one electrodes of the plural cylindrical battery cells in parallel through the first spacer 21.</p> |
