The present invention has an object of providing a sugar derivative emitting blue fluorescence color which can be used for imaging of cells or intracellular molecules and a method for imaging cells using the derivative. Further, the present invention has an object of providing a method for detecting cancer cells at high accuracy by imaging, and an imaging agent used for this method. The present invention provides a fluorescently labeled sugar derivative having 3-carboxy-6,8-difluoro-7-hydroxycoumarin or 3-carboxymethyl-6,8-difluoro-7-hydroxy-4-methylcoumarin as a fluorescent molecular group in its molecule, and a cell imaging agent and an imaging method using the derivative. Further, the present invention provides an imaging agent and an imaging method for cancer cells using an L-glucose derivative having the above-described fluorescent molecular group in its molecule.
