A vehicle body rear structure is provided with a battery pack disposed in a floor recess of a rear floor panel. The battery pack includes battery modules, a pair of front suspended frame and rear suspended frame that hold the battery modules at the front and rear ends in such a manner that the battery modules are suspended from a vehicle body, and load path members through which the front suspended frame and the rear suspended frame are coupled to each other. The front suspended frame and the rear suspended frame have flanged collars and through-holes that are fastened to rear frames and fragile portions that are provided in the vicinity of the flanged collars and the through-holes and at which the front suspended frame and the rear suspended frame are bent forward when the vehicle body is subjected to an impact load in a rear-end collision.
