Abstract
The present invention relates to an optical filter, a solid-state imaging element and an imaging device lens which contain a near infrared ray absorbing layer having a specific near infrared ray absorbing dye dispersed in a transparent resin having a refractive index of 1.54 or more, and also relates to an imaging device containing the solid-state imaging element or the imaging device lens. The near infrared ray absorbing layer has a transmittance of visible light of from 450 to 600 nm of 70% or more, a transmittance of light in a wavelength region of from 695 to 720 nm of not more than 10%, and an amount of change of transmittance of not more than −0.8.
