Abstract: A front vehicle-body structure of a vehicle includes: side frames of a suspension subframe; a cross member connecting front-end portions of the side frames in the vehicle width direction; a front beam member; and a connecting member connecting a front-end portion of each side frame to the front beam member. A high-rigidity portion having a higher rigidity than other portions of the side frame is at a connecting portion between the front-end portion of the side frame and the cross member. The front beam member has a side end portion extending on a vehicle-width-direction outer side relative to a connecting position with the connecting member. A protrusion portion protruding from the side end portion toward a vehicle rear side is to come into contact with the high-rigidity portion from the vehicle-width-direction outer side when a collision load from a vehicle front side is input to the side end portion.
