To provide a face image pickup apparatus for a vehicle which can image a bright spot on a driver's eyeball correctly by an imaging means even if the driver wears glasses.
A CCD camera 20 for imaging a driver m's face and a near-infrared LED 21 for irradiating light to the driver m's eyeball 27 for detection of the eye direction are arranged at forward side from the steering wheel 13. The CCD camera 20 and the near-infrared LED 21 are disposed to separate mutually from more than a predetermined distance in the vertical direction and the width direction of the vehicle. Here the predetermined distance is set in such a distance that a bright spot on the glasses where the light of near-infrared LED 21 reflects on the glasses 25 and a bright spot on the eyeball where the light of near-infrared LED 21 reflects on the eyeball 27 are imaged with no overlap on the CCD camera 20.
