Provided are a near infrared ray absorbent composition which can form a cured film having excellent near infrared ray shielding properties, a near infrared ray cut filter, a manufacturing method of a near infrared ray cut filter, a solid image pickup element, and a camera module. The near infrared ray absorbent composition includes a copper complex that is other than a copper phthalocyanine complex and has a maximum absorption wavelength in a wavelength range of 700 to 1,200 nm and in which a molar light absorption coefficient at the maximum absorption wavelength is greater than or equal to 100 (L/mol·cm).

The near infrared absorbing composition includes: a copper-containing polymer having a copper complex site at a polymer side chain; and a solvent, in which the copper complex site includes a site multidentate-coordinated to a copper atom and at least one selected from the group consisting of a site monodentate-coordinated to a copper atom and a counter ion to a copper complex skeleton, and a polymer main chain and a copper atom at the copper complex site are bonded to each other through the site monodentate-coordinated to a copper atom or the counter ion.
