[Problem] In a battery pack having a battery unit in which plural cell groups are connected in series, and a protection circuit board to protect by detecting intermediate electric potentials, tap portions of lead plates in the battery unit and terminals of the protection circuit board are easily connected. [Solution] In a battery unit (10), tap portions (101a-114a) are provided in the order of the electrical potential at the upper end portions of lead plates (101-114), along both right and left sides of a setting surface (11). Pivot portions (51 a, 51 b) of a circuit unit (20) are press-fitted into, and are pivotally coupled to bearing portions (52, 53). At assembling, pivotally coupling is done and the tap portion (101 a) of the minimum electrical potential is connected to a terminal portion (26), and according to rotating and setting the circuit unit (20) on the setting surface (11), lead pins (202-213) connected to terminal portions (252-263) of the circuit unit (20) are connected to the corresponding tap portions (102a-113a) in order.
