    • An optical element includes: a first optical layer having a concavo-convex surface; a wavelength-selective reflective layer provided on the concavo-convex surface of the first optical layer; a second optical layer provided on the concavo-convex surface on which the wavelength-selective reflective layer is provided so as to fill the concavo-convex surface, and in the optical element described above, the wavelength-selective reflective layer includes a metal layer, a protective layer provided on the metal layer and containing a metal oxide as a primary component, and a high refractive index layer provided on the protective layer and containing a metal oxide other than zinc oxide as a primary component, and the wavelength-selective reflective layer selectively directionally reflects light in a specific wavelength band while transmitting light other than that in the specific wavelength band.
    • 光学元件包括:具有凹凸表面的第一光学层; 设置在第一光学层的凹凸表面上的波长选择性反射层; 设置在其上设置有波长选择反射层的凹凸表面以填充凹凸表面的第二光学层,在上述光学元件中,波长选择反射层包括金属层, 设置在金属层上并含有金属氧化物作为主要成分的保护层和设置在保护层上并含有除氧化锌以外的金属氧化物作为主要成分的高折射率层,以及波长选择反射层 选择性地定向反射特定波长带中的光,同时透射特定波长带以外的光。
