To provide a vehicle body front part structure which enables a lower bulk member to be easily collapsed when a load is input to improve pedestrian protection.SOLUTION: A vehicle body front part structure includes: a pair of left and right front side frames 12 extending along a vehicle fore and aft direction; a pair of left and right upper members 14 extending along the vehicle fore and aft direction; a front bulkhead 18 attached to the pair of left and right front side frames 12 and extending along a vehicle width direction; and a pair of left and right connection members 16 provided between the respective upper members 14 and the front bulkhead 18. The front bulkhead 18 includes a lower bulk member 38 disposed at the lower side. The lower bulk member 38 has a fragile part 44 which is located at the vehicle front side relative to the connection member 16 in the vehicle fore and aft direction and extends in the vehicle width direction.SELECTED DRAWING: Figure 3
