PROBLEM TO BE SOLVED: To provide an organic dye complex having a wider area of absorption wavelengths, especially a wider area of absorption wavelengths in a near-infrared region.SOLUTION: There is provided a composite of a specific phthalocyanine derivative and a porphyrin derivative having a structure of the formula (2). In the formula (2), A, B, C and D represent each independently a hydrogen atom, a halogen atom or a monovalent organic group, at least two of the A to D are substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl, M2 represents at least one atom or atom group that may bind with porphyrin. |
