The present invention provides an oil-in-water type emulsion composition which exhibits excellent temporal and temperature stability and produces a good feeling of use, and a method for producing same. Emulsification is carried out by means of a specific intermediate phase formed by mixing a surfactant able to form a L [alpha] phase, a surfactant able to form a H1 phase, and water. The intermediate phase preferably has an interfacial tension of 0.01-8 mN/m as a relative value with respect to poly(perfluoromethyl isopropyl ether). The oil-in-water type emulsion composition is produced by means of a production method that includes a step of adding an oil phase component and an aqueous phase component in that order to the intermediate phase. In addition, it is preferable to use a combination of a first surfactant and a second surfactant so that the viscosity of a mixed aqueous solution of the first and second surfactants is less than half of the sum of the viscosity values of individual aqueous solutions of the first and second surfactants having concentrations that are the same as the overall concentrations of the surfactants in the mixed aqueous solution.本發明提供一種歷時及溫度穩定性優良，且可發揮良好的使用感之水中油型乳化組成物、及其製造方法。經由藉由可形成Lα相之界面活性劑、可形成H1相之界面活性劑與水的混合所生成的特定之中間相來進行乳化。前述中間相較佳具有以相對於聚全氟甲基異丙基醚的相對值表示為0.01~8mN/m的界面張力。藉由包含對前述中間相依序添加油相成分及水相成分之步驟的製造方法，來製造水中油型乳化組成物。又，較佳為使用第一及第二界面活性劑之混合水溶液的黏度小於與前述混合水溶液之界面活性劑的總濃度同濃度的第一或第二界面活性劑之各水溶液的黏度之合計的1/2的第一及第二界面活性劑之組合。
