To provide a car body front structure capable of effectively absorbing an impact load from ahead of the car body and securing a greater wind quantity to a radiator.

The car body front structure includes a bumper 30 which is installed ahead of a radiator panel 10 having a lower frame 12 and whose two ends are supported by the front extremities of a left and a right front frame 20, wherein the bumber 30 has a lower bumper beam 43 confronting the front face of the lower frame 12, an upper bumper beam 42 installed above the lower bumper beam 43, and an outer air introducing hole 53 penetrating between the lower 43 and upper bumper beams 42 in the direction fore and aft of the car body. Thereby the lower bumper beam 43 moved backward upon being deformed by the impact load from ahead of the car body is received by the lower frame 12 without increasing the area covering the front of the radiator, and the impact energy is transmitted to the left and right front frames 20 and absorbed in dispersion over the whole car body effectively, and the outer air is introduced from the hole 53.
