PROBLEM TO BE SOLVED: To provide an organic polymeric phosphorescent compound able to be formed into films from the solution of an organic solvent, water or the like in a wet process and bring the films to have large surface areas at low cost, stable and having long life and able to emit very high efficient phosphorescence in the material of an organic phosphorescent element, and also provide an organic phosphorescent element using the phosphorescent compound.SOLUTION: The phosphorescent compound is soluble in an organic solvent or water and includes a phosphorescent unit which is a repeat unit for emitting phosphorescence, and a carrier transporting unit which is a repeat unit for transporting a carrier, in the main chain or side chains of the polymeric compound.
