Abstract
Provided is a battery pack capable of improving volumetric efficiency while reducing the thickness of the entire battery. The battery pack is configured by laminating a plurality of film-sheathed batteries () each including power generating element () and film sheath material () in which internal space () is formed for housing power generating element () along with an electrolyte. Power generating element () includes main surfaces () that are positioned on both sides in a lamination direction, and side surfaces () that are adjacent to main surfaces (). Film sheath material () includes housing part () that is provided with main surface covering sections () for covering main surfaces () and side surface covering sections () for covering side surfaces (), main surface covering sections () and side surface covering sections () forming internal space (), and sealing parts () that protrude from side surface covering sections () to seal internal space (). In one film sheath material, sealing partsare bonded to side surface covering sections () of the other film sheath material that is adjacent to the one film sheath material in the lamination direction.
