To obtain a thin film layer used for an organic electroluminescent element and the like, and to obtain the organic electroluminescent element with high luminous efficiency of which, a hole transport layer with large area can be easily manufactured.

The polymeric hole transport material is composed of a copolymer of vinyl monomer having substituent, and acrylate or methacrylate having unsaturated group. The substituent is at least one group chosen from carbazole group, carbazole derivative group, triphenylamine, and triphenylamine derivative group. It is preferable that the unsaturated group is aliphatic unsaturated hydrocarbon residue with 2 to 20 carbons, and that the distribution ratio of the vinyl monomer having substituent to the total monomer of the copolymer ranges between 0.5 to 0.9, and that the degree of polymerization of the copolymer ranges between 10 and 1,000. The organic electroluminescent element has more than one layer of organic thin film having the light emitting layer as a minimum between the positive electrode and the negative electrode, and the light emitting layer and/or the organic thin film contacting with the light emitting layer includes this polymeric hole transport material.
