Zusammenfassung:	Provided is a polishing composition for a silicon oxide film that can improve the speed of polishing a silicon oxide film. In one or more embodiments, a polishing composition for a silicon oxide film contains: water; a cerium oxide particle; and a compound having in its molecule an amino group and at least one acid group selected from a sulfonic acid group and a phosphonic acid group. In the polishing composition, [the number of moles of the acid group contained in the compound]/[total surface area of the cerium oxide particle] is in a range from 1.6×10−5 mol/m2 to 5.0×10−2 mol/m2.
