A face image taking device including a two-dimensional image taker for taking an image of a predetermined region including a face of a person to be detected; an optical filter having a pass band passing at least an infrared ray in a predetermined wavelength region and arranged on an optical axis of the two-dimensional image taking; an eye detector for detecting eyes of the person to be detected based on the image of the face of the person to be detected which has been taken by the two-dimensional image taker; an infrared ray illuminator for illuminating at least the face of the person to be detected by an infrared ray which has passed through the optical filter, said infrared ray illuminator being arranged such that an angle made by the optical axis of the two-dimensional image taker and an optical axis of the infrared ray is a predetermined angle or more; and an exciting means for exciting the infrared ray illuminator when the eye detector does not detect the eyes of the person to be detected.
