PROBLEM TO BE SOLVED: To provide an organic EL element having a response speed so high as to be used as a light emitting element for optical communication purposes such as an optical interconnect module. SOLUTION: Provided is the organic electroluminescent element in which a light emitting layer is made of a material including one or more kinds selected from the group consisting of DPVBi, PBD, DSB, and BCzVBi and fluorescence lifetime of the light emitting layer is≤3.0 ns. Also provided is the organic electroluminescent element in which the light emitting layer is made of a material including one or more kinds selected from the group consisting of DPVBi, PBD and DSB, and fluorescence lifetime of the light emitting layer is≤0.6 ns.
