description Provided is a thermally activated delayed fluorescence-emitting organic EL element having a low driving voltage, high luminous efficiency, and a prolonged lifespan. The organic EL element contains one or more light-emitting layers between an anode and a cathode that face each other, and at least one light-emitting layer contains a host material composed of a carbazole compound represented by formula (1) and a thermally activated delayed fluorescence material composed of an indolocarbazole compound containing an indolocarbazole ring in its molecule. Here, L1 represents an aromatic group, and at least one R1 represents a carbazolyl group, and n is 1 or 2.
