PROBLEM TO BE SOLVED: To provide a line-of-sight detection device capable of accurately detecting the line-of-sight direction of various subjects. A line-of-sight detection device displays a display unit that displays an index image, a light source that irradiates the eyeball of a subject with detection light, and an image of the eyeball that is irradiated with the detection light to determine the centers of the pupils of the left and right eyes. A curvature that calculates the corneal radius of curvature of each of the left and right eyes from the position detection unit that detects the position of the center of the pupil shown and the position of the center of corneal reflection that indicates the center of corneal reflection, and the position of the light source and the position of the center of corneal reflection. A radius calculation unit, a line-of-sight detection unit that detects the line-of-sight directions of the left and right eyeballs from the position of the center of the pupil and the radius of curvature of the cornea, and the viewpoints of the left and right eyes are detected from the line-of-sight directions detected by the line-of-sight detection unit. The visual point detection unit and the output control unit that causes the visual point of each of the left and right eyes detected by the visual point detection unit to be displayed on the display unit on which the index image is displayed.
