Abstract: The present invention provides a polarizing glass with better heat resistance than a conventional polarizing glass and an optical isolator including the polarizing glass. In the polarizing glass, metal layers in which many substantially needle-shaped metal fine particles are dispersed to be oriented parallel to one another are formed from both surfaces toward inside and a metal halide layer containing metal halide fine particles is formed between the metal layers. A total thickness of the polarizing glass is smaller than 0.12 mm, a thickness of each of the metal layers is 0.030 to 0.045 mm, and a thickness of the metal halide layer is 0.001 to 0.040 mm. Alternatively, the total thickness of the polarizing glass is smaller than 0.12 mm, the thickness of each of the metal layers is 0.010 to 0.030 mm, and the thickness of the metal halide layer is 0.001 to 0.060 mm.

Abstract: A light shielding film made up of a material containing one or more elements selected from silicon and tantalum and a hard mask film made up of a material containing chromium, oxygen, and carbon are laminated on a transparent substrate. The hard mask film is a single layer film having a composition gradient portion with increased oxygen content on the surface and on the neighboring region. The maximum peak for N1s in a narrow spectrum obtained via X-ray photoelectron spectroscopy analysis is the lower limit of detection or less. The portions excluding the composition gradient portion of the hard mask film have a 50 atom% or more chromium content, and the maximum peak for Cr2p in a narrow spectrum obtained via X-ray photoelectron spectroscopy analysis has a binding energy of 574 eV or less.
