Optical Member and Window Material
Provided is an optical member including: an optical layer including a first optical layer having a surface with a concave-convex shape, a reflective layer disposed on the surface with the concave-convex shape of the first optical layer, and a second optical layer disposed on the reflective layer; a first transparent substrate disposed on a side of the first optical layer included in the optical layer; and a second transparent substrate disposed on a side of the second optical layer included in the optical layer. The reflective layer is configured to reflect near-infrared light, and the first transparent substrate and the second transparent substrate are made of a same material. The optical member has a total thickness of not more than 125 μm, a breaking strength of not less than 100 N, and a break elongation both before and after a weatherability test of not less than 60%.
