PROBLEM TO BE SOLVED: To provide a novel light emitter which has a triplet light-emitting complex structure in the molecule and can form a light-emitting layer by coating. SOLUTION: The polymeric light emitter has a number average molecular weight, in terms of polystyrene, of 10<SP>3</SP>to 10<SP>8</SP>and a metal complex structure which exhibits light emission from the excited triplet state in the main chain or in the side chain. The metal complex structure which exhibits light emission from the excited triplet state is a polymeric light emitter having a structure to be represented by formula (6) (wherein M is an atom having an atomic number of≥50 and a metal capable of causing the interstate crossing between the singlet state and the triplet state by the spin-orbit interaction in the complex; Ar is a ligand which bonds M with at least one of a nitrogen atom, an oxygen atom, a carbon atom, a sulfur atom or a phosphorus atom; L is a hydrogen atom, an alkyl group, an aryl group, a heterocyclic ligand or the like; m is an integer of 1-5; and o is an integer of 0-5).
