PROBLEM TO BE SOLVED: To provide a vehicle body bone structure having sufficient strength on practical use by simple structure and joint work in which coupling strength is enhanced without a coupling plate even if vertical and lateral bones are laser-welded to an outer plate. SOLUTION: When the bones 1, 2 arranged in vertical and lateral sides are welded/joined 5 to the outer plate 3 while one end 2a has a relationship opposed to the other side surface, the other bone 1 is abutted while laid on the end 2a of one bone 2 welded/joined to the outer plate 3 and the outer plate 3 and the other bone 1 is welded/joined 4, 6 to both of these to accomplish the above object.
