PROBLEM TO BE SOLVED: To provide a vehicle body front structure capable of avoiding load concentration in the axial direction of a longitudinal skeleton member by dispersing the load at the time of a frontal collision, and preferably transmitting a load in the axial direction of the longitudinal skeleton member even if a collision with a low lap rate occurs. SOLUTION: In each pair of the plurality pairs of the upper and lower longitudinal skeleton members 2, 3, 17, a curvature rate is applied to front end portions 2A, 3A, 17A, and the curvature application direction of the front end portion 2A of the one pair of the longitudinal bone members 2 is set to be different from the direction of the other pairs of the longitudinal skeleton members 17, therefore the front end portions 2A, 3A, 17A of the longitudinal skeleton members 2, 3, 17 incline on the opposite side to the center of the curvature rate when the front surface of the vehicle collides, curvature deformation is gradually proceeded, and a collision contact area is increased in the curvature deformation direction, the load is dispersed in the increase direction, and the curvature application directions of the respective pairs are different, thus compensating for mutual faults in strength.
