PROBLEM TO BE SOLVED: To provide a water-in-oil emulsified cosmetic excellent in water repellency and oil repellency, and also excellent in preservation stability. SOLUTION: The water-in-oil emulsified cosmetic comprises (A) fluorine modified silicone represented by general formula (1), (B) silicone oil containing a perfluoroalkyl group, (C) and polar oil. In the formula (1), Rf is a 1-20C perfluoroalkyl group, R<SP>1</SP>, R<SP>2</SP>, R<SP>4</SP>, R<SP>5</SP>, R<SP>6</SP>and R<SP>7</SP>are a 1-4C straight or branched chain monovalent hydrocarbon group or a phenyl group, R<SP>3</SP>is a monovalent hydrocarbon group having an average carbon number of >20 and≤50, R<SP>8</SP>is a 1-4C monovalent hydrocarbon group or a monovalent hydrocarbon group having an average carbon numbers of >20 and≤50, m is an integer of 2 to 3, n is an integer of 1 to 6, p is a number of 1 to 50, and q and r are each a number of 0 to 50, however, q is a number of 1 to 50 when R<SP>8</SP>is a 1-4C monovalent hydrocarbon group.
