To achieve an excellent solar radiation shielding properties and a visible light reflectance of at least 70%, the interlayer portion of the laminated glass of the present invention includes a heat reflecting film and a film having a heat shielding function that is provided between the heat reflecting film and the second glass sheet. The first pattern has a substantially planar upper surface by which parallel light is specularly reflected. A plurality of coupling-matching layers are positioned between one or more of the stack mirror arrangements for controlling optical phase and coupling strength between emitted or incident light and resonant modes in each of the stacked cavity arrangements.
