The organic electroluminescent material contains a host and a dopant. the host contains an organic electroluminescence-functional portion A formed of a low-molecular organic electroluminescent material and a soluble portion B bonded to the organic electroluminescence-functional portion A for solubilizing the low-molecular organic electroluminescent material in the solvent, the host being represented by a formula of A-B-E (where E represents a terminal group). The portion A is a low-molecular organic electroluminescent material having a central anthracene skeleton. The portion B is formed by bonding structures represented by the following formula (3) with structure(s) represented by the following formula (4). Units represented by the formula (3) include bonds in ortho positions or meta positions while unit(s) represented by the formula (4) includes bonds in para positions.
