NEAR-INFRARED-ABSORBING COMPOSITION, NEAR-INFRARED CUT-OFF FILTER USING SAME, MANUFACTURING METHOD THEREFOR, CAMERA MODULE, AND MANUFACTURING METHOD THEREFOR

摘要

An object of the present invention is to provide a near-infrared-absorbing composition capable of forming a cured film having excellent heat resistance while maintaining strong near-infrared shielding properties when a cured film is produced. The near-infrared-absorbing composition of the present invention includes a copper complex obtained by reacting two or more kinds of sulfonic acids represented by General Formula (I) described below or salts thereof with a copper component and a solvent.
