To produce scaly silica particles in which formation of irregular particles is prevented. A process for producing scaly silica particles, which comprises a step of subjecting a silica powder containing silica agglomerates having scaly silica particles agglomerated, to acid treatment at a pH of at most 2, a step of subjecting the silica powder subjected to the acid treatment, to alkali treatment at a pH of at least 8 to deflocculate the silica agglomerates, and a step of wet disintegrating the silica powder subjected to the alkali treatment to obtain scaly silica particles. |
