An organic electroluminescent element (1) has a light-emitting layer (5) present between an anode (3) and a cathode (4), wherein the light-emitting layer (5) contains a fluorescent first compound represented by general formula (1), a delayed-fluorescence second compound represented by general formula (2), and a third compound represented by general formula (3). The singlet energy S1(M1) of the first compound, the singlet energy S1(M2) of the second compound, and the singlet energy S1(M3) of the third compound satisfy the relationship in the expression in formula (1).　Formula (1): S1(M3) > S1(M2) > S1(M1) |
