    Abstract: The present invention provides a laminate having excellent clearness of reflected light without impairing visibility of an image, a visual-line tracking system using the laminate, and a head-mounted display on which the visual-line tracking system is mounted.
    The laminate including a near infrared light reflecting layer and a near infrared light absorbing layer, in which a visible light transmittance of the laminate is 60% or more, the near infrared light absorbing layer contains a near infrared absorbing compound, and the following expressions (1) and (2) are satisfied.


    Δθ1≤3°  (1)



    R2/R1≤0.1  (2)



    Δθ1: a half-width of a peak of near infrared reflected light with the highest intensity, which is obtained from a measurement result of an angle dependence of intensity of near infrared light reflected by the near infrared light reflecting layer
    R1: the highest intensity of near infrared reflected light among peaks of the near infrared reflected light obtained from the measurement result of the angle dependence of the intensity of near infrared light reflected by the near infrared light reflecting layer
    R2: the second highest intensity of near infrared reflected light among the peaks of the near infrared reflected light obtained from the measurement result of the angle dependence of the intensity of near infrared light reflected by the near infrared light reflecting layer
