    摘要： An object of the present invention is to provide a polymer compound capable of achieving a satisfactory brightness even at a low driving voltage when it is applied to a light-emitting device. A polymer compound according to a preferred embodiment includes multiple first groups and a block (A) comprising a structure in which the first groups are linked by a second group represented by formula (0-0), and includes at least one of a group represented by formula (0-1) or a group represented by formula (0-2) as the first group;


    wherein Ar 0 represents an optionally substituted arylene group or an optionally substituted divalent aromatic heterocyclic group which has a structure different from that of the first group; n represents an average chain length in terms of Ar 0 and is a numerical value of 1.0 or more and 8.0 or less; and X 11 to X 16 and X 21 to X 25 each represent a carbon atom or a nitrogen atom, where two or three of X 11 to X 16 are a nitrogen atom and three of X 21 to X 25 are a nitrogen atom.
