An apparatus for viewing an oblique forward area of a vehicle whereby light incident from outside a passenger compartment is prevented from reflecting. The apparatus includes a sub-window pane supported by a front pillar and a sub-pillar, a mirror housing of a door mirror for displaying a rear of the vehicle, and a first reflective mirror for displaying an area in front and to one side of the vehicle. The first reflective mirror is provided to the mirror housing. The apparatus also includes a second reflective mirror for reflecting the light reflected by the first reflective mirror toward a driver. The sub-window pane is disposed further toward the outside in a vehicle widthwise direction than a line passing over cross-sectional vehicle-widthwise direction centers of the front pillar and the sub-pillar. An outside edge of the second reflective mirror is positioned in the vicinity of the sub-window pane.
