Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery assembly in which a voltage detection line can be arranged while minimizing increase in physique.SOLUTION: A battery pack 11 is a battery assembly constituted by connecting a plurality of battery cells 10, each having a terminal at the peripheral edge of a planar exterior case 12, in series or parallel. A voltage detection line 15 is provided so as to detect the voltage between the terminals 13, 14 of the battery cell 10 as an electric signal. The exterior case 12 is formed of a laminate film 16, and the internal space of the battery cell 10 is formed by sticking the peripheral edges of the laminate film 16 by heat welding. Furthermore, the voltage detection line 15 is arranged along the surface of a heat welding portion 17 in the exterior case 12.
