PURPOSE:To obtain the titled cosmetic, capable of suppressing volatilization of a volatile oil with time as well as improved breaking strength and having excellent usability, by coating and protecting an inner phase consisting of an oil cosmetic base containing a volatile oil with a oily solid base containing a specific solid oil. CONSTITUTION:A stick-like cosmetic having a structure of integrated an inner phase part with outer phase part, the inner phase part consisting of an oily cosmetic base containing 3-30wt% volatile oil, the outer phase consisting of an oily solid base containing 20-80wt% solid oil. A volatile hydrocarbon oil or volatile silicone oil having <=300 deg.C boiling point is used as the volatile oil and carnauba wax, microcrystalline wax, etc., having >=60 deg.C melting point are used as the solid oil. The aimed substance is obtained by casting the molten oily solid base into a molding vessel, solidifying the oily slid base, removing the central part to form a hollow cylindrical outer phase part, filling the molten oily cosmetic base containing the volatile oil therein, solidifying and integrally molding the above-mentioned parts.
