An optical member includes a base material and a laminate structure having two types of layers with different types of material arranged on the base material. The laminate structure is constituted by10 or more layers. The maximum thickness of a layer that is part of the laminate structure is 8 nm or less, and the minimum transmittance in the wavelength range from 400 nm to 800 nm or from 6 [mu]mto 12 [mu]m is 10% or greater. 一种光学部件，其具备：基材；及层叠结构，配置于所述基材上且由材质不同的2种以上的层构成，构成所述层叠结构的层的数量为10以上，构成所述层叠结构的层的最大层厚为8nm以下，400nm～800nm的波长范围或6μm～12μm的波长范围内的最低透射率为10％以上。
