PURPOSE: To obtain an emulsion used for cosmetic treatment (e.g. replenish of nutrient, hydration or protection) of the skin, and an emulsion used for preparation of a cream for treating disease of the skin (e.g. dry skin). CONSTITUTION: This water-in oil type emulsion contains fine solid spherical particles of a polyalkylsilasesquioxane, ensuring the dispersion of the aqueous phase in the oil phase without surfactant, and includes the fine spherules of water having 100 nm-20 μm diameter. The solid spherical particles are (A) particles obtained by carrying out surface treatment of silica obtained by thermal degradation method by using a (halogenated) alkylsilane, and having <14 nm diameters, or (B) particles obtained by polymerizing an alkoxyalkylsilane and having 100-800 nm diameters, and included in the emulsion in 1-10 wt.%, preferably 2-5 wt.%. The amount of the oil introduced to the emulsion is preferably within the range of 60-75 wt.% in the case of the particles A and 45-55 wt.% in the case of the particles B.
