A probe comprising a long tube of generally cylindrical shape, a cap for sealing a distal end of the tube, a pair of light emitting diodes fixed to inside of a recess of the cap, two systems of leads connected to the light emitting diodes, respectively, and a lid for sealing the recess of the cap. When the two systems of leads are supplied with drive currents alternately, the light emitting diodes emit excitation light for exciting tissue of a living body to emit self fluorescence and visible light for illuminating the subject, respectively and alternately.
