To provide an inspection device for an optical disk, which inspects the printed face of a label 111 using transparent or fluorescent ink of an optical disk such as a CD, inspects the state of a protective coating film 113, or inspects the lamination and adhesion state of a laminated DVD or the like.

The inspection device 200 for the optical disk is equipped with an LED illumination unit 4 to illuminate the surface of an optical disk to be inspected with near UV rays from a near UV LED 8, near IR rays from a near IR LED 9, and visible rays from a visible ray LED 10 at a time, with a beam splitter 3 to spectrally divide the reflected light of the rays from the optical disk 110 into near UV rays and visible rays from near IR rays, with a near IR camera 1 to photograph the visible light and the near IR rays spectrally divided by the beam splitter 3, and with a near UV camera 2 to photograph the near UV rays spectrally divided by the beam splitter 3.
