This invention provides a flaky glass comprising a flaky glass base material and a covering film covering the surface of the flaky glass base material. The flaky glass base material has an average thickness of 0.1 to 1.0 µm and an average diameter of 1 to 100 µm. The covering film is formed of a methylhydrogensilicone, and the content of the covering film is 0.05 to 2.50% by mass in terms of ignition loss as measured at 625 ± 20ºC. Cette invention porte sur un verre en paillettes comprenant un matériau de base de verre en paillettes et un film de recouvrement recouvrant la surface du matériau de base de verre en paillettes. Le matériau de base de verre en paillettes a une épaisseur moyenne de 0,1 à 1,0 µm et un diamètre moyen de 1 à 100 µm. Le film de recouvrement est formé d'un méthylhydrogénosilicone, et la teneur du film de recouvrement est de 0,05 à 2,50% en masse en termes de perte au feu telle que mesurée à 625 ± 20ºC.
