Provided is a glucose derivative, which is taken into cells via a membrane sugar transport system and is represented by formula (1). Also provided are an imaging agent and an imaging method for a cell or intracellular molecule using said glucose derivative. Further provided are a method for detecting cancer cells with good accuracy using said glucose derivative and an imaging agent to be used in said method. More specifically provided are D-glucose derivatives and L-glucose derivatives in which glucose is bound to the 7-position of a fluorescent molecular group with a coumarin backbone or a quinolone backbone. Also provided are a cell imaging agent and imaging method using the derivative. A cancer cell imaging agent and imaging method using the L-glucose derivative is also provided. G is a group selected from formulas (G1)-(G4) below.
