PROBLEM TO BE SOLVED: To provide a vehicle body structural member and a collision-proof reinforcing member capable of suppressing increase of weight of a hollow structural member and the number of parts to the minimum extent to improve impact absorbing property against vehicle collision. SOLUTION: This vehicle body structural member is constituted in such a way that an aluminum alloy hollow extrusion 6a for reinforcement is extended over the direction of width or the longitudinal direction of the hollow structural member 1a inside the hollow structural member 1a constituted by a formed panel. The hollow extrusion 6a has a curved shape 11 in which a part of the hollow extrusion 6a overhangs toward the direction of vehicle body collision determined for the hollow structural member in the longitudinal direction to constitute an impact absorbing part for vehicle body collision to the hollow structural member by joining with an inner member 3 in both end parts 12a, 12b of the hollow extrusion 6a.
