The present invention addresses the problem of providing: a near-infrared absorbing composition which exhibits excellent absorption characteristics in the near-infrared region, while having high dispersibility and high visible light transmittance; and a near-infrared absorbing film and an image sensor for solid-state imaging elements, each of which uses this near-infrared absorbing composition. A near-infrared absorbing composition according to the present invention contains a near-infrared absorbent and a solvent, and is characterized by containing, as the near-infrared absorbent, a compound that contains the component (A) and the component (B) described below, while having a structure represented by formula (I) in an amount within the range of 0.001-10% by mass. Component (A): a component that is composed of a compound represented by general formula (1) or general formula (2), a compound represented by formula (I) and a copper ion Component (B): a component that is composed of a compound represented by general formula (1) or general formula (2), a compound represented by formula (I) and a copper complex Formula (I): O=P-(OH)3 |
