PROBLEM TO BE SOLVED: To further enhance a close contact force between an ultraviolet curing- type cation-polymerizable adhesive layer and an ultraviolet curing ink layer (a decoration layer or an organic protective layer), which comes into contact with the layer in a single-sided recording-type optical recording medium or a double-sided recording-type optical recording medium in which two disks are pasted by the ultraviolet curing-type cation-polymerizable adhesive layer. SOLUTION: This optical recording medium is formed in such a way that an optical recording disk 3 in which an optical recording layer 2 is formed on a first substrate 1, and a dummy disk 6 in which an optical recording layer may be formed on a second substrate 4 are pasted by an ultraviolet curing-type cation-polymerizable adhesive layer 7 in such a way that the first substrate 1 and the second substrate 4 are situated at the outside. When an ultraviolet curing ink layer 5 is formed between the optical recording disk 3 and the adhesive layer 7 or between the dummy disk 6 and the adhesive layer 7, the surface resistance value of the ultraviolet curing ink layer 5 is set at 1.0×1014 Ω or higher. |
