PROBLEM TO BE SOLVED: To provide a material for a light-emitting element of which the lowest driving voltage is low; the luminance is high, and the decrease in luminance after high-temperature storage is small. SOLUTION: This material for a light-emitting element is a polymer represented by the formula (wherein R3 is an aryl, heterocyclic, aralkyl, alkyl or polymerizable group; and R4 is an aryl or heterocyclic group).
