A lower vehicle-body structure of a vehicle is provided with a frame member having a closed-cross section. The frame member comprises a first portion and a second portion. The first portion comprises a compression face portion and a pair of side face portions. The side face portion comprises a bending portion, a compression-side area which is positioned on a side of the compression face portion relative to the bending portion and where a compressive stress is generated when the bending load is applied, and a tension-side area which is positioned on a side away from the compression face portion relative to the bending portion and where a tensile stress is generated when the bending load is applied. The compression-side area is configured to have higher rigidity than the tension-side area.
