Abstract: A vehicle body front structure provided with left and right side frames (16, 17). The left front side frame (16) has a rectangular closed cross-sectional shape. The front side frame (16) is provided with a rectilinear section (front half frame section) (44) extending rectilinearly from the front end (58) to the center section (43), and also with a moment receiving section (rear half frame section) (45) continuing from the rectilinear section (44) and extending in a curved form toward the inner side in the widthwise direction of the vehicle. A first ridge line section (78) is a portion which forms a corner (78) among the corners (78) of the rectilinear section (45), said corner (78) being located on the inner side in the widthwise direction of the vehicle. A second ridge line section (84) is connected to the first ridge line section (78) at a position inside the moment receiving section (45). A stiffener (65) is connected to the rear end (66) of the front side frame (16).
