Provided is a highly water dispersible powder which exhibits a high water dispersibility in spite of the inclusion of a poorly water soluble component, and maintains the high water dispersibility stably over time. The highly water dispersible powder includes a poorly water soluble component, a water soluble polymer having a protective colloid effect, and a saponin. The highly water dispersible powder can be produced by a method including: emulsifying a poorly water soluble component in an aqueous solvent under the presence of a water soluble polymer having a protective colloid effect and a saponin, thereby preparing an emulsion; and drying the obtained emulsion.
