A front portion of a vehicle body includes front side frames, a subframe, and a vehicle compartment front structure body. The subframe has a subframe body, a leg portion, a front fastening portion, and a rear fastening portion. The front side frame has a subframe mounting portion which is arranged on a front side of a bending starting point and to which the front fastening portion is fastened. A component mounting bracket having an inclined guide portion with a front surface inclining downward toward a vehicle rear side is coupled to a rear side of the bending starting point of the front side frame. The inclined guide portion is arranged on a track in which the leg portion detached from the front side frame is displaced rearward when an impact load is input from the front of the vehicle.
