The present invention discloses a polymer material comprising a fluorescent or phosphorescent compound. When used in a light emitting device, the polymer material can obtain a light emitting device having excellent practicability, which can be driven at a low voltage, and is excellent in luminous efficiency, hue of luminescence, and the like. Specifically, the present invention discloses a polymer material characterized by comprising: a structure of polymer (A) or (A) having a residue of a compound represented by the following formula (1); and Structures of molecules (B) or (B) showing fluorescence or phosphorescence in . (1) (In the formula, each of rings A, B, and C independently represents an optionally substituted aromatic ring or non-aromatic ring; Z 1 , Z 2 , Z 3 , Z 4 , and Z 5 independently represent C-(Q)z or a nitrogen atom; Q represents a substituent or a hydrogen atom; z represents 0 or 1; rings A and B can share atoms in the ring except Z 5 ; and rings A, B and C One or both rings are non-aromatic). |
