PROBLEM TO BE SOLVED: To provide a blue light-emitting polymer that has high color purity, low drive voltage, high efficiency, particularly improving the chromatic coordinate in the blue color area, controls the increase of required brightness and can overcome the defect of short life, and provide an organic electroluminescent element using the same. SOLUTION: In an organic electroluminescent element equipped with an organic film between a pair of electrodes, a bisindenospirofluorene-based unit structure compound is used as the main chain of a polyarylene polymer.
