Abstract: An infrared-emitting compound has a structure represented by the following Formula (1a). In Formula (1a), Ar and ring A each independently represent an aryl ring, a heteroaryl ring or a fused ring thereof. Q-Ar represents an infrared-emitting residue. R1 represents a group in which a dihedral angle between Ar and ring A is 45 degree or more. And a thick line represents a single bond or a double bond.
