PROBLEM TO BE SOLVED: To provide a composition for an organic electroluminescent element, which has a low foreign matter content.SOLUTION: The present invention relates to the composition for an organic electroluminescent element, which is for forming at least one layer selected from the group consisting of a light-emitting layer, a hole injection layer, and a hole transport layer of an organic electroluminescent element and contains an aromatic amine-based polymer having a weight-average molecular weight of 3,000-1,000,000 and an organic solvent. The content of the aromatic amine-based polymer is 0.05 wt.% or more. The Zn concentration in the composition is less than 0.5 ppm. |
