An information recording medium is formed by laminating a transparent protective layer and a base material having laser color-developing properties. The information recording medium includes an intermediate layer that is disposed between the transparent protective layer and the base material. In the information recording medium, the intermediate layer includes a diffraction structure layer that has a diffraction structure, and a first reflective layer that reflects visible light and is destroyed when irradiated with a laser beam. Light, when incident from a transparent protective layer side, causes a diffracted light pattern to appear in the diffraction structure layer so as to be observable from the transparent protective layer side. A laser beam, when applied from the transparent protective layer side, passes through the diffraction structure layer, destroys the first reflective layer, and develops color in the base material.
