Abstract

PROBLEM TO BE SOLVED: To obtain an element emitting light of a plurality of wave lengths. SOLUTION: A disc-like infrared light emitting diode 2 is arranged on a base 1 constituting a package. An infrared light emitting diode 3 having a smaller diameter than the diode 2 is stacked concentrically on the upper surface of the diode 2 and a blue light emitting diode 4, having a smaller diameter than the diode 3, is stacked concentrically on the upper surface of diode 3. Upper end faces thereof serve as light emitting surfaces for emitting the light concentrically in the same direction toward the light incident end 5a of an optical fiber 5 disposed above the package oppositely thereto.
