An optical recording medium includes a support substrate, a light transmission layer whose one surface constitutes a light incidence plane through which a laser beam is projected, an information recording layer formed between the support substrate and the light transmission layer, a reflective layer formed between the information recording layer and the support substrate, a water proof layer formed between the reflective layer and the support substrate and containing a mixture of ZnS and SiO<SUB>2 </SUB>as a primary component, and a corrosion resistant layer formed between the water proof layer and the reflective layer. According to the thus constituted optical recording medium, it is possible to effectively prevent a reflective layer from being corroded and has excellent storage reliability.
