摘要：
In a vehicle body structure in which a vehicle-body frame of front side frames 2 with a flangeless structure having a rectangular closed cross section and a vehicle-body panel of a dash panel 1 are welded, a concave portion 15 is formed at a specified portion of the vehicle-body panel to which the vehicle-body frame is welded so as to be concaved toward one side which is opposite to a disposition side of the vehicle-body frame and extends in its longitudinal direction, a temporary connection portion 16 which temporarily connects the vehicle-body frame to a side of the concave portion 15 is formed, and a laser welding portion 17 which connects the vehicle-body frame to the vehicle-body panel is formed near the temporary connection portion 16 so as to extend along the longitudinal direction of the vehicle-body frame.
