Near infrared light for a solid-state imaging device or a light receiving device capable of expanding the choice of materials and enhancing the degree of design freedom such as downsizing according to needs while satisfying the performance of near infrared light cut Provided are an optical cut filter, and an imaging device, a solid-state imaging device, and an imaging device lens including the same. An imaging apparatus 101 according to the present invention includes a near-infrared light cut filter 1 that shields near-infrared light between a subject and a photoelectric conversion element 62. The near-infrared light cut filter 1 includes the optical member 10, the antireflection layer 30 formed on the surface of the second main surface 12 of the optical member 10, the second main surface 12 of the optical member 10, and / or the first. And a near-infrared shielding layer 20 formed on the main surface 11. The near-infrared shielding layer 20 includes a selective wavelength reflection layer 21R in which a liquid crystal phase having a right rotation direction of at least one set of helical axes is fixed, and a selective wavelength reflection in which a liquid crystal phase having a rotation direction of a helical axis is fixed. The layer 21L is laminated. [Selection] Figure 2A |
