There is provided a fluorescent dye which can improve the fluorescent intensity at the time of labeling to thereby detect a biomolecule with higher sensitivity. The fluorescent dye of the present invention includes a nitrogen cation-containing group or a nitrogen-containing group. Its high water solubility can improve the rate of labeling for a biomolecule to thereby detect a biomolecule with high sensitivity.
