Abstract: A laminated body includes a transparent substrate having a laminated film. The laminated film includes a dielectric layer containing silicon nitride, a barrier layer composed of a single film or two or more films, and a metal layer containing silver. The barrier layer has a thickness of from 0.1 nm to 10 nm. Each film of the barrier layer includes a material having a crystal structure of a face-centered cubic structure with a lattice constant of from 3.5 to 4.2, a hexagonal close-packed structure with a lattice constant of from 2.6 to 3.3, a body-centered cubic structure with a lattice constant of from 2.9 to 3.2, or a tetragonal crystal with a lattice constant of from 2.9 to 4.4. The metal layer has a thickness of from 7 nm to 25 nm. An orientation index P of the metal layer falls within a range from 4.5 to 20.

Abstract: The present invention relates to a light-transmitting ceramic sintered body which contains air voids having pore diameters of 1 μm or more but less than 5 μm at a density within the range of from 10 voids/mm3 to 4,000 voids/mm3 (inclusive), while having a closed porosity of from 0.01% by volume to 1.05% by volume (inclusive). With respect to this light-transmitting ceramic sintered body, a test piece having a thickness of 1.90 mm has an average transmittance of 70% or more in the visible spectrum wavelength range of 500-900 nm, and the test piece having a thickness of 1.90 mm has a sharpness of 60% or more at a comb width of 0.5 mm.
