PROBLEM TO BE SOLVED: To provide a method for purifying trimethylindium by which high-purity trimethylindium can easily, surely and economically be obtained. SOLUTION: The method for purifying the trimethylindium includes: heating and dissolving the trimethylindium produced from trimethylaluminum and an indium halide with normal hexane; then carrying out cooling and recrystallizing; and affording the high-purity trimethylindium. As a result, there are exhibited industrial profits that the trimethylindium can easily be purified; the constitution of production equipment and size of the production equipment can be reduced; waste disposal thereafter can readily be carried out; and cost of wastes can be reduced.
