Disclosed is an aromatic diamine derivative represented by the following general formula (I), which has a chrysene structure in which a phenyl group having a substituted or unsubstituted silyl group is a substituent for an amino group. Also disclosed is an organic electroluminescence device including an organic thin film layer formed of one or more layers including at least a light emitting layer and interposed between a cathode and an anode, in which at least one layer of the organic thin film layer contains the aromatic diamine derivative by itself or as a component of a mixture, the device having a long lifetime and high luminous efficiency. (In the formula, R1 to R10 each independently represent a hydrogen atom, an alkyl group having 1 to 50 carbon atoms, or the like, and R11 represents a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms or the like, and at least one of A, B, and C represents a substituted or unsubstituted silyl group, and the others each represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, or the like, a, b, c, and d each independently represent an integer of 1 to 5.) |
