A novel electroluminescence polymer offers stable EL characteristics: it forms little aggregates and is less susceptible to morphological changes during and after film formation. The EL polymer comprises a binaphthyl derivative structural unit represented by the following formula (1a) and an aryl structural unit represented by the following formula (1b):
wherein Ar is an aryl structural unit that can form an electroluminescent π-conjugated polymer; R

are each independently a different functional group; the double bonds of the binaphthyl structural unit indicated by dashed lines and solid lines are each an unsaturated double bond or a saturated single bond; m and p are each independently an integer of 0 to 2; n and o are each independently an integer of 0 to 8; x is the molar fraction of the binaphthyl derivative structural units; and y is the molar fraction of the aryl structural units.
