An aluminum chelate complex which is effective in stabilizing the degree of vacuum in a film deposition chamber during a vapor deposition step and which gives at a high production efficiency a high-quality organic EL element having excellent reliability and withstanding practical-level use. The organic EL material is an aluminum chelate complex which is represented by L<1>Al(L<2>)2 and in which the content of complexes represented by Al(L<2>)3 is 0.6 mol% or lower. This complex is obtained by reacting an aluminum alkoxide with a quinolinol derivative, subsequently reacting the reaction product with a phenolic compound to form a complex, and purifying the complex to a high degree. In the formula, L<1> represents a phenolate ligand and L<2> represents a substituted 8-quinolilate ligand.
