The invention provides a method for manufacturing infrared shieldA near-infrared absorbent composition, a film, an infrared cut filter, a solid-state imaging element, an infrared absorbent and a compound, each of which is a film having excellent properties and visible transparency. A near-infrared absorbent composition contains a squarylium salt compound represented by the following formula (1) and having a maximum absorption wavelength of 700nm or more, and a resin. In the formula, Ar 1 And Ar 2 Each independently represents a divalent conjugated group having a hetero aromatic ring containing a chalcogen atom, R 1 ～R 4 Each independently represents a hydrogen atom or a substituent. The film and the infrared cut filter are composed of a near-infrared absorbent composition. The solid-state imaging element has an infrared cut filter. |
