To provide a polymer compound having high charge injecting property, transporting property, and high luminous efficiency. Hole injection transport including a fluorenediyl group which may have a substituent as a repeating unit in the main chain and containing a hetero atom other than one or more nitrogen atoms or two or more nitrogen atoms At least one selected from the group consisting of a group, an electron injecting and transporting group containing one or more heteroatoms other than nitrogen atoms or two or more nitrogen atoms, and a light emitting group containing a condensed polycyclic aromatic hydrocarbon or a heterocyclic ring A light-emitting or charge-transporting polymer compound having a functional side chain containing one functional group, wherein the functional group is directly bonded to the saturated carbon of the fluorenediyl group, or -R The above-mentioned polymer compound, wherein X is bonded to the fluorenediyl group through X-X- (R k represents an alkylene group, X represents a direct bond or a linking group).
