    摘要： The optical element of the present invention has an anti-reflection film formed on a substrate. The anti-reflection film comprises a low refractive index layer that is formed by mutually binding hollow fine particles, each of which has a vacancy therein, using a binder, and the low refractive index layer consists of a first layer serving as an outermost layer and a second layer which is adjacent to the first layer and is located on the substrate side. Here, the filling ratio of the binder to the first layer is lower than the filling ratio of the binder to the second layer, the refractive index of the first layer is 1.1 or more but not more than 1.25 and the refractive index of the second layer is 1.26 or more but not more than 1.35.

    摘要： Provided is an ND filter including an alternating layer which is composed of two films being alternately stacked and formed on a transparent substrate, the two films having different refractive indexes, wherein the alternating layer has a substrate-side reflected light attenuating multi-layered film and a transmittance adjusting multi-layered film formed on the transparent substrate in the stated order from the transparent substrate side, and the light absorption amount of the substrate-side reflected light attenuating multi-layered film is set to be 20% or more and 30% or less. Thus, an ND filter having satisfactory front surface reflection characteristics and rear surface reflection characteristics can be stably obtained while the transmittance of 4% or more and 11% or less is maintained with respect to the entire visible region (400 nm or more and 700 nm or less).
