According to the present invention, options for materials for organic devices such as materials for organic EL elements are increased by addition of a cycloalkane, by condensation, to a polycyclic aromatic compound in which a plurality of aromatic rings are linked together by boron atoms, oxygen atoms, and the like. By using a novel cycloalkane-condensed polycyclic aromatic compound as a material for an organic EL element, for example, an organic EL element having excellent emission efficiency and element life is provided.
