Abstract
Provided is a battery pack in which multiple battery cells are electrically connected by using bus bars, with little resistance variability and without plating of electrode external terminals. A method for producing a battery pack disclosed herein includes: a step of stacking a plurality of battery cells each having a battery case and electrode external terminals provided outside the battery case; and a step of electrically connecting the electrode external terminals of the plurality of battery cells by using metal-made bus bars. The electrode external terminals are not plated. The method for producing a battery pack further includes forming a fresh surface of terminal material at each surface of the electrode external terminals; and bringing the fresh surface and each metal-made bus bar into contact with each other.
