A viewing direction detector includes: an infrared light irradiation unit that uses an infrared light source to irradiate an infrared light; a projection unit that causes the infrared light to be reflected by a windshield or a combiner, and projected in a direction towards an eye of a user; an image acquisition unit that acquires, from an infrared camera for imaging the eye from a direction different to the direction in which the infrared light enters the eye, an infrared camera image having a range including the eye; a recognition unit that recognizes a pupil and a Purkinje image in the infrared camera image acquired by the image acquisition unit; and a viewing direction detection unit that detects the viewing direction of the user from the positional relationship between the pupil and the Purkinje image recognized by the recognition unit.
