Abstract: According to the present invention, a dummy terminal is provided on a sensing substrate and the sensing substrate may be thus commonly used on both side surfaces of a battery module, and as a result, since only one type of sensing substrate provided with the dummy terminal needs to be manufactured instead of manufacturing two types of sensing substrates having different arrangements of the substrate terminals, mass productivity of the sensing substrate and the battery module including the same may be significantly improved.
