| 摘要 |
A laminated structure which has a substrate formed of a synthetic resin or glass and a silicon carbide coating layer formed by sputtering, wherein the light transmittance of the silicon carbide coating layer is 80% or less. Preferably, the silicon carbide coating layer has a light reflectance of 10 to 50%, the synthetic resin is polycarbonate, the impurity ratio on the surface of the silicon carbide coating layer is 1.0x1012 atoms/cm2 or less, and the silicon carbide layer has a thickness of 15 to 100 nm. The laminated structure is suitable for a recording medium such as a CD-ROM and a DVD-ROM since it has a silicon carbide layer excellent in oxidation resistance, chlorine resistance, moisture resistance, and the like.
