PROBLEM TO BE SOLVED: To provide a polymer compound used for producing a light-emitting device having a long operating life and a high luminous efficiency in good balance. SOLUTION: The polymer compound has a conjugated polymer main chain and a side chain selected from the following (a), (b) and the like: (a) is a side chain having an electron transport property. The value of the LUMO energy of this side chain is different from that of the LUMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less; (b) is a side chain having a hole transport property. The value of the HOMO energy of this side chain is different from that of the HOMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less.
