1. A vehicle body structure, comprising a panel formed by a steel plate having a tensile strength of 440 MPa or more,
wherein the panel has a bead extending in a predetermined direction over an entire surface, and
the direction in which the bead extends and the type of the bead are set so as to reduce a difference between a peak load and an average load at the time of collision,
wherein the panel is a rear floor panel; and
the rear floor panel comprises:
a plurality of lateral beads that extend in a direction orthogonal to a load input direction at the time of collision and line up in the load input direction; and
a plurality of vertical beads that extend in the load input direction, line up in the direction orthogonal to the load input direction, and connect the plurality of lateral beads adjacent to each other.
