PROBLEM TO BE SOLVED: To provide a battery pack, a battery and a connection joint which can prevent corrosion of terminals even in the case of connecting terminals made of different metals. SOLUTION: The battery pack is composed of more than two serially connected secondary batteries 1 including an electrode 11, a laminate film 14 enclosing the electrode 11, and a positive terminal 12 and a negative terminal 13 both of which are connected to the electrode 11 and projected from the laminate film 14. A joint of terminals of adjacent secondary batteries 1 is covered with an insulation film 15 at least in a part of whole of projected part of the terminal having higher self-potential (the negative terminal 13) from the laminate film 14 except for a part (an exposed part 18) used for the connection with the terminal of an adjacent battery (the positive terminal 12).
