A main object of the present invention is to provide: fine particles whose excitation light is not the one such as UV light or the like which has negative effects on a subject to be analyzed, emit light stably, and has excellent light emitting efficiency, and a fluorescent probe labeled with the fine particles.
In order to achieve the aforementioned object, the present invention provides a fluorescent probe comprising: fine particles containing a rare earth element characterized in that they are excited by light having a wavelength in a range of 500 nm to 2000 nm and thereby emit up-conversion emission; and a specific binding substance which binds to the fine particles containing a rare earth element.
