PROBLEM TO BE SOLVED: To realize the high luminescent efficiency and superior driving durability by using a compound having a specific structure in an electron carrying layer as at least one organic layer held between a pair of electrodes. SOLUTION: This organic electroluminescent element has an electron carrying layer including a compound represented by the formula as a component, as one of organic layers formed between a pair of electrodes. In the formula, M is a tetravalent metal, preferably zirconium; R1-R5 are H, chlorine atom, bromine atom, alkyl halide group, lower alkyl group, lower alkoxy group, aralkyl group, an optionally substituted aryl group, a dialkylamino group, a diphenyl group or the like. By using the tetravalent metal as a central metal, the electron carrying property of a molecule can be improved, and the luminescent efficiency and the driving durability of the element can be improved. The organic layer is preferably used as a luminescent layer. The balance of a hole and electron in the luminescent layer is improved, and the luminescent efficiency can be improved.
