Abstract: The purpose/problem of the present invention is to provide a method for producing tungsten complex oxide particles useful as a heat shield material or the like that permits inexpensive production of a stable composition. This method for producing tungsten complex oxide particles includes a step for preparing a dispersion in which a raw material powder has been dispersed, a step for feeding the dispersion into a thermal plasma flame, and a step for supplying gas containing oxygen to the terminal portion of the thermal plasma flame and producing tungsten complex oxide particles. The dispersion preferably includes a carbon element.
