Abstract: A purpose of the present invention is to provide an oil-in-water emulsion composition that is stable even when using solid oils from which it was conventionally considered to be difficult to form large oil-based particles exceeding 50 μm, and also improving the uniformity of the particle sizes and the shapes of the oil-based particles. The present invention relates to an oil-in-water emulsion composition in which oil-based particles containing a solid oil, a liquid oil and a powder are dispersed in a water phase, wherein: the oil-based particles have an average particle size of 50 μm to 10 mm; and the powder is contained inside the oil-based particles.
