A driver's eye condition detection is conducted by an eye condition detection apparatus including a right/left near-infrared light sources, a camera and an ECU installed therein. The right side near-infrared light source is positioned on a right side relative to the camera in a driver's view, and a light axis of the right side near-infrared light source is tilted to the right by 15 to 45 degrees relative to an imaging direction of the camera. Further, the left side near-infrared light source is positioned on a left side relative to the camera in a driver's view, and a light axis of the right side near-infrared light source is tilted to the left by 15 to 45 degrees relative to an imaging direction of the camera. In this manner, detection errors of the driver's eye condition are reduced.
