A near infrared absorbing colorant polymer has a maximal absorption in a wavelength range of 700 to 1200 nm. It is preferable that the near infrared absorbing colorant polymer includes at least one near infrared absorbing colorant structure selected from the group consisting of a pyrrolopyrrole colorant, a cyanine colorant, a squarylium colorant, a diimonium colorant, a phthalocyanine colorant, a naphthalocyanine colorant, a rylene colorant, a dithiol complex colorant, a croconium colorant, an oxonol colorant, a triarylmethane colorant, a pyrromethene colorant, an azomethine colorant, an anthraquinone colorant, and a dibenzofuranone colorant.
