In order to provide a battery having excellent vibration resistance and shock resistance, this battery is characterized by having: an electrode laminated body 60 formed by laminating a positive electrode 20, a negative electrode 30, and a separator 40; and a laminate film exterior material 80 that houses the electrode laminated body 60 and an electrolytic solution. The battery is also characterized in that the static friction coefficient between the negative electrode 30 and the inner surface of the laminate film exterior material 80 is 0.1 or more. |
