PROBLEM TO BE SOLVED: To provide a polymeric compound which, when used for a polymeric luminous element, exhibits a high luminescent efficiency. SOLUTION: The polymeric compound includes one or more kinds of repeating units selected from the group consisting of repeating units represented by formula (1), repeating units represented by formula (2), and repeating units represented by formula (3). In formula (1), R<SP>3</SP>is an alkyl group; R<SP>1</SP>and R<SP>2</SP>are each independently an alkyl, alkoxy, alkylthio, arylalkyl, arylalkoxy, arylalkylthio, arylalkenyl, arylalkynyl, amino, substituted amino, silyl, substituted silyl, halogen, acyl, acyloxy, imine residue, acid amide, monovalent heterocyclic, carboxyl, substituted carboxyl, cyano, or nitro group; a and b are each independently an integer of 0-3; and Z is -O- or -S-.
