Provided is a fluorescent light-emitting material for improving the light-emitting efficiency of an organic light-emitting element such as an organic EL element or an organic PL element, and also provided is an organic light-emitting element that uses the fluorescent light-emitting material. The fluorescent light-emitting material is formed from a compound which has an indolocarbazole skeleton represented by general formula (1). The organic light-emitting element is an organic EL element that has a light-emitting layer between a cathode and an anode laminated on a substrate, and that includes as host materials the organic light-emitting material, which is contained in the light-emitting layer, and an organic compound having higher excitation triplet energy than the organic light-emitting material. In general formula (1), ring A is an aromatic ring represented by formula (1a) that is condensed with an adjacent ring, ring B is a heterocycle represented by formula (1b) that is condensed with an adjacent ring, Ar is an aromatic hydrocarbon group or an aromatic heterocyclic group, R is hydrogen or a monovalent substituent group, and n is an integer between 1 and 4. |
