OPTICAL ELEMENT, SOLAR SHADING DEVICE, FITTING, WINDOW MATERIAL, AND METHOD FOR MANUFACTURING OPTICAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an optical element which partially reflects incident light thereon to suppress the rise of an ambient temperature and is free from delamination to be excellent in durability, and to provide a solar shading device, a fitting, a window material, and a method for manufacturing the optical element.SOLUTION: An optical element includes a shaped layer 11, an optical functional layer 13, and an embedding resin layer 12. The shaped layer 11 has a structure 11a forming recessed portions 111. The optical function layer 13 is formed on the structure 11a, and reflects infrared rays thereon and transmits visible light therethrough. The embedding resin layer 12 has a structure layer 12a (first layer) which fills the recessed portions 111 and has a first volume, and a flat layer 12b (second layer) formed on the structure layer 12a with such a thickness as to have a second volume that is 15% or more of the first volume. The embedding resin layer 12 is formed of ultraviolet curable resin in which the structure 11a and the optical functional layer 13 are embedded.SELECTED DRAWING: Figure 5
