A specific silole derivative, e.g., one represented by general formula (1), is incorporated into an organic electroluminescent element. Thus, the element can have a high efficiency and a long life. In formula (1), R1 and R2 each independently represents optionally substituted alkyl, silyl, aryl, heterocycle, or alkenyl and may be bonded to each other at the ends; Ar1 and Ar2 each independently represents optionally substituted aryl or heterocycle; and R3 to R10 each independently represents optionally substituted alkyl, aryl, or heterocycle and may be bonded to each other at the ends. |
