Abstract:
A laminated structure comprising a substrate formed of a synthetic resin or glass and a silicon carbide coating layer formed on the substrate by sputtering, wherein a sintered silicon carbide, the impurity ratio on or near the surface of the sintered silicon carbide being 1.0Ã—1011 atoms/cm2 or less, and having a high density, a high purity and a volume resistivity of 100 &OHgr;Â·cm or less is used as a target material, wherein the silicon carbide coating layer has a light transmittance of 80% or less and a volume resistivity of 100 &OHgr;Â·cm or less and an impurity ratio of 1.0Ã—1011 atoms/cm2 or less.
