PROBLEM TO BE SOLVED: To provide a polymer compound useful as a light-emitting material and an electron-transport material, and excellent in element characteristics such as heat resistance. SOLUTION: The polymer compound comprises a recurring unit shown in formula (1) as a principal component, wherein X<SB>1</SB>and X<SB>2</SB>each independently represents a bivalent condensed polycyclic aromatic hydrocarbon group having three rings or more or a bivalent condensed polycyclic heterocyclic group having three rings or more; Y<SB>1</SB>represents a unicyclic or bicyclic bivalent aromatic hydrocarbon group, a unicyclic or bicyclic bivalent heterocyclic group, or a bivalent group having an amine structure comprising a unicyclic or bicyclic aromatic hydrocarbon, or a unicyclic or bicyclic heterocyclic group, or a metal complex structure.
