The printed makeup product of the present invention includes a base sheet 1, an inorganic solid layer 3 provided on the base sheet, and an ink-jet printed image 5 formed on the inorganic solid layer 3. A makeup material is applied onto the ink-jet printed image 5. The surface of the inorganic solid layer 3, upon observation in an electron micrograph at a magnification of 100, is a rough surface where indefinitely shaped protrusions are present in a proportion of 10 to 30% per unit area. Of the indefinitely shaped protrusions, 50 to 300 of them per mm^(2) are observed having a major diameter of 10 to 300 m.
