Abstract
To provide a near-infrared absorption composition which contains a squarylium compound having excellent solvent solubility, a cured film which uses the near-infrared absorption composition, a near-infrared cut filter, a solid-state imaging device, an infrared sensor, and a compound. A near-infrared absorption composition includes a compound represented by the following Formula (1) and a resin. R1 and R2 each independently represent “—S1-L1-T1” or the like, R3 and R4 each independently represent a hydrogen atom or an alkyl group, X1 and X2 each independently represent an oxygen atom or —N(R5)—, R5 represents a hydrogen atom or the like, Y1 to Y4 each independently represent a substituent, p and s each independently represent an integer of 0 to 3, and q and r each independently represent an integer of 0 to 2; and S1 represents an arylene group or the like, L1 represents an alkylene group or the like, and T1 represents an alkyl group or the like.
