In a floor cross member configured by a web surface () as the top surface, a ridge part () contiguous to the web surface (), and a vertical wall surface () contiguous to the ridge part (), having a tensile strength of 440 MPa or larger, flanges () are formed at both longitudinal ends continuously around at least the web surface (), the ridge part () and the vertical wall surface (), and the floor cross member () is connected through the flanges () to a tunnel part () and to a side sill (). The flange () has a flange width l, at the center in the perimeter direction of the curved part (-), not smaller than the minimum flange width lof the curved part (-). Accordingly, a vehicle body, which is suppressed in deformation of the floor cross member () and improved in the torsional rigidity, is successfully provided. 1. A vehicle body comprising a longitudinal member disposed as aligned in the front-back direction of the vehicle body , and a widthwise member disposed as aligned in the widthwise direction of the vehicle body ,the widthwise member having at least a web surface which configures the top surface, a ridge part contiguous to the web surface, and a vertical wall surface contiguous to the ridge part,the widthwise member having a flange formed at the longitudinal end continuously around at least the web surface, the ridge part and the vertical wall surface, and being connected through the flange to the longitudinal member,{'sub': fc', 'fs, 'the flange having a flange width l, at the center in the perimeter direction of the curved part thereof, being not smaller than the minimum flange width lin the region excluding the center in the perimeter direction of the curved part, and'}the widthwise member having a tensile strength of 440 MPa or larger.2. The vehicle body according to claim 1 , wherein the widthwise member is a press-molded body having a ditch-like transverse cross-sectional shape.3. The vehicle body according to claim 1 , wherein the ridge part has a radius ...
