Abstract

A solar-shading light-transmissive panel has a light-transmissive sheet, an absorbing layer disposed on said light-transmissive sheet, a first transparent dielectric layer disposed on said absorbing layer, an Ag-rich layer comprising Ag as a main component disposed on said first transparent dielectric layer, and a second transparent dielectric layer disposed on said Ag-rich layer. The solar-shading light-transmissive panel, which basically has the four layers and can be manufactured relatively inexpensively, has an ornamentally excellent appearance, a relatively high solar-shalding capability, and a relatively high visible light transmittance.
