Abstract: An optical filter, includes: a near infrared ray absorbing glass, dielectric multilayer films laid on or above both major surfaces of the near infrared ray absorbing glass, and an absorption layer laid on or above a surface of at least one of the dielectric multilayer films and having a maximum absorption wavelength in a near infrared light region, in which the optical filter satisfies all of spectral characteristics (i-1) to (i-5).
