NOVELTY - An organic electronic element has a hole block layer (18), or an electron block layer (17) formed on upper portion of an organic layer which is interposed between a transparent electrode (12) and a counter electrode (13). The organic layer is formed using a coating liquid containing alkyl group-containing compound (I).    USE - Organic electronic element is used for organic photoelectric conversion element and organic electroluminescent element (both claimed). Can also be used for silicon-type solar cells, compound semiconductor-type solar cells, and dye-sensitized-type solar cells.    ADVANTAGE - The organic electronic element has high durability. The organic photoelectric conversion element using the organic electronic element has excellent photoelectric conversion efficiency. The organic electroluminescent element using the organic electronic element has high luminous efficiency.    DETAILED DESCRIPTION - An organic electronic element has a hole block layer, or an electron block layer formed on upper portion of organic layer which is interposed between a transparent electrode and a counter electrode. The organic layer is formed using a coating liquid containing pyridine-containing compound of formula: (R1-L1)-B (I). The content of compound (I) is 0.01-10% with respect to total solid content of the organic layer.    R1=optionally substituted 2C or more alkyl, cycloalkyl, haloalkyl, or halocycloalkyl;    L1=single bond, sulfur atom, nitrogen atom, silicon atom, germanium atom, arylene, heteroarylene, alkenylene, or alkynylene (all optionally substituted);    B=mother nucleus having hole-blocking property and larger highest occupied molecular orbital (HOMO) energy level than material having maximum HOMO, or mother nucleus having electronic block property and lesser lowest unoccupied molecular orbital (LUMO) energy level than material having minimum LUMO;and    n=1-4.    INDEPENDENT CLAIMS are included for the following:    (1) organic photoelectric conversion element (11), which has organic electronic element, where bulk heterojunction layer containing p-type semiconductor material and fullerene derivative as n-type semiconductor material is used as organic layer; and    (2) organic electroluminescent element, which has organic electronic element, where the phosphorescence light-emitting layer containing light-emitting host material and iridium complex as light-emitting dopant material is used as organic layer.
