The invention aims at providing a novel azaaromatic compound having an azafluoranthene skeleton which is useful as the constituent of organic EL devices and at realizing a long lifetime, high-efficiency and practical organic EL device by using the compound in at least one of the organic compound layers. The invention provides azaaromatic compounds having azafluoranthene skeletons as represented by the general formula (1): wherein R

to R
12
may be linked together to form a ring structure.
