<p>A power supply apparatus 1 includes: a battery cell assembly 2 including battery cells 3 having a positive terminal 11 at one end and a negative terminal 12 at the other end; a busbar module 5 attached to the assembly 2 and configured to connect the cells 3 in series with each other; and a pair of electric wires 9 connected to electrodes 11, 12 taking out a voltage of the series-connected cells 3. The busbar module 5 includes: bus bars 6 configured to connect the positive terminal 11 and the negative terminal 12 of the mutually adjacent battery cells 3 of the assembly 2; a plate 8 disposed on the assembly 2 with the bus bars 6 attached thereto; and an electric wire holding portion 18 provided on the plate 8 configured to hold one electric wire 9a of the pair of the electric wires 9. The electric wire holding portion 18 extends in the arrangement direction X in which the cells 3 are arranged at a central portion of the plate 8 in the width direction Z orthogonal to the direction X of the battery cells 3.</p> |
