PROBLEM TO BE SOLVED: To provide a transition metal complex capable of efficiently providing a polymer, especially capable of introducing a polar monomer into an olefin in high content, and further to provide a catalyst containing the complex, and a method for producing an olefinic copolymer obtained by using the catalyst. SOLUTION: Ethanol is reacted with N,N-dimethylethylenediamine and salicylaldehyde, and the residue obtained by concentrating the reaction liquid is purified to provide salicylideneamine derivative. The salicylideneamine derivative is reacted with methanol and sodium borohydride, and a diamine compound is separated from the concentrate obtained by concentrating the reaction liquid. The resultant diamine compound is reacted with chloro(methyl) (1,5- cyclooctadiene)palladium (II), potassium carbonate and dried dichloromethane, and the objective transition metal complex is obtained as a precipitate formed by adding n-pentane to the concentrate of the obtained reaction liquid.
