A vehicle battery pack housing structure includes a vehicle body panel and first, second and third panel components that define an outward-opening battery housing space. The first panel component is rigidly attached to the vehicle body panel and includes a first side wall and a base wall. The second panel component is rigidly attached to the first panel component and includes a second side wall and a first periphery wall portion. The third panel component is rigidly attached to the second panel component. The third panel component includes a second periphery wall portion that cooperates with the first periphery wall portion to form a periphery wall portion when the third panel component is rigidly attached to the second panel component.
