Summary:PROBLEM TO BE SOLVED: To provide a compound for an organic EL element, having little influence of concentration quenching even when the concentration of a dopant material based on the total of the light-emitting organic compound is heightened, and providing sufficient light-emitting efficiency when used for the organic EL element, and to provide the organic EL element using the compound. SOLUTION: The compound for the organic EL element is represented by general formula (1) (wherein, X1to X18are each independently a hydrogen atom or the like, with the proviso that X3, X4, X8, X12, X13and X17satisfy at least one condition in the following conditions (i) and (ii): (i) X8and X17are each independently a 12-20C aryl group; and (ii) at least one of X3, X4, X12and X13is an aryl group which may have a substituent, or a heterocyclic group which may have a substituent).
