Using the fluorescent group-containing carbodiimide compound represented-by the following formula (I) as the label and the like in the nucleic acid detection method, immunoassay, or chemiluminescence assay, labeling can be made efficiently for a short time, a nucleic acid derived from nature can be labelled, and highly sensitive assay is enabled.B-Y3-N=C=N-Y2-W-Y1-[A]n-F(I)wherein F represents a fluorescent group; A represents a moiety selected from the group consisting of -CH2-, -NHCO-, -CONH-, -O-, -S-, -NR- wherein R is an alkyl group, -COO-, -OCO-, -NHSO2-, and -SO2NH-; n is 0 or 1; W represents a direct bond or a quaternary ammonium group; Y1, Y2 and Y3 each represents an alkylene group which may have a functional group in its main chain; and B represents H or a monovalent organic group which may be the same as or different from that represented by -W-Y1-[A]n-F.
