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.
