Abstract
An infrared-absorbing composition according to the present invention includes: an infrared absorber formed by a phosphonic acid represented by the following formula (a) and copper ion; and a phosphoric acid ester allowing the infrared absorber to be dispersed. The phosphoric acid ester includes at least one of a phosphoric acid diester and a phosphoric acid monoester. Ris a phenyl group or a phenyl group in which at least one hydrogen atom is substituted by a halogen atom. When molar contents of the phosphonic acid, the copper ion, and the phosphoric acid ester are respectively defined as Cmol, Cmol, and Cmol and a total molar content of reactive hydroxy groups is defined as Cmol, the relations C/C<1 and C/C>1.95 are satisfied.
