An organic EL device includes an anode, an emitting layer, an electron transporting zone and a cathode in this sequence, in which the electron transporting zone contains an aromatic heterocyclic derivative represented by a formula (1) below. In the formula (1), X1 to X3 are a nitrogen atom or CR1, and A is represented by a formula (2) below. In the formula (2), L1 is s single bond or a linking group, and HAr is represented by a formula (3) below. In the formula (3), Y1 is an oxygen atom, a sulfur atom or the like, and one of X11 to X18 is a carbon atom bonded to L1 by a single bond and the rest of X11 to X18 are a nitrogen atom or CR13.
(HAr)a - L1- (2)
