PURPOSE: To improve durability, transparency and function for controlling transmissivity by arranging a hotmelt film having a prescribed m.p. and a plastic film on the surface of a selective light transmitting film laminated between plural glass plates.
CONSTITUTION: The selective light transmitting film 2 is obtained by forming a thin film of In2O3/silver or the like on one side face of polyethylene terephthalate 50μm in film thickness. Next, the hotmelt film 5 about 50μm in thickness is obtained by forming a film of polyamide resin having 80-140°C m.p. The film 5 is superposed on the surface of the film 2 and furthermore the plastic film 6 having ≥140°C m.p. is superposed thereon and is pressed to obtain a protective layer. The laminated glass is formed by holding the protective layer between joining materials 4, 4', furthermore holding this between a transparent glass panels 1, 1' and pressing at about 120°C and about 10kg/cm2.
