A fender supporting portion structure comprising: vehicle body skeleton portions that are disposed along a vehicle longitudinal direction at both sides of a vehicle body front portion, and that have first supporting portions whose supporting surfaces face toward a vehicle upper side, and second supporting portions that are provided at intervals with respect to the first supporting portions and whose supporting surfaces face toward the vehicle upper side and whose height positions in a vehicle vertical direction are set to be lower than those of the first supporting portions; and brackets for energy absorption that cause the vehicle body skeleton portions to support inner side end portions of upper portions of fender panels and whose cross-sectional shapes are formed in hat-shapes, and that have fender mounting portions to which the inner side end portions of the upper portions of the fender panels are fixed, first vehicle body side mounting portions that are fixed to the first supporting portions, second vehicle body side mounting portions that are fixed to the second supporting portions, first supporting leg portions that join the fender mounting portions and the first vehicle body side mounting portions in the vehicle vertical direction, and second supporting leg portions that join the fender mounting portions and the second vehicle body side mounting portions in the vehicle vertical direction and whose lengths in the vehicle vertical direction are set to be longer than those of the first supporting leg portions, wherein a first bent portion, that is bent so as to be convex toward a side opposite a side of the second supporting leg portion and that has a first ridgeline that extends in a horizontal direction, is formed at an upper portion of the first supporting leg portion, a second bent portion, that is bent so as to be convex toward a side opposite a side of the first supporting leg portion and that has a second ridgeline that extends in the horizontal direction, is formed at an upper portion of the second supporting leg portion, and a region at a vehicle vertical direction intermediate portion of the first supporting leg portion, which region is further toward a lower side than the first bent portion, and a region at a vehicle vertical direction intermediate portion of the second supporting leg portion, which region is further toward a lower side than the second bent portion, are connected by a connecting portion. vehicle body skeleton portions that are disposed along a vehicle longitudinal direction at both sides of a vehicle body front portion, and that have first supporting portions whose supporting surfaces face toward a vehicle upper side, and second supporting portions that are provided at intervals with respect to the first supporting portions and whose supporting surfaces face toward the vehicle upper side and whose height positions in a vehicle vertical direction are set to be lower than those of the first supporting portions; and brackets for energy absorption that cause the vehicle body skeleton portions to support inner side end portions of upper portions of fender panels and whose cross-sectional shapes are formed in hat-shapes, and that have fender mounting portions to which the inner side end portions of the upper portions of the fender panels are fixed, first vehicle body side mounting portions that are fixed to the first supporting portions, second vehicle body side mounting portions that are fixed to the second supporting portions, first supporting leg portions that join the fender mounting portions and the first vehicle body side mounting portions in the vehicle vertical direction, and second supporting leg portions that join the fender mounting portions and the second vehicle body side mounting portions in the vehicle vertical direction and whose lengths in the vehicle vertical direction are set to be longer than those of the first supporting leg portions, wherein a first bent portion, that is bent so as to be convex toward a side opposite a side of the second supporting leg portion and that has a first ridgeline that extends in a horizontal direction, is formed at an upper portion of the first supporting leg portion, a second bent portion, that is bent so as to be convex toward a side opposite a side of the first supporting leg portion and that has a second ridgeline that extends in the horizontal direction, is formed at an upper portion of the second supporting leg portion, and a region at a vehicle vertical direction intermediate portion of the first supporting leg portion, which region is further toward a lower side than the first bent portion, and a region at a vehicle vertical direction intermediate portion of the second supporting leg portion, which region is further toward a lower side than the second bent portion, are connected by a connecting portion.
