Abstract: The present invention provides a method for producing an inorganic particle-containing slurry, by which the number of coarse particles can be sufficiently reduced. The present invention is a method for producing an inorganic particle-containing slurry, which comprises: a step of preparing an inorganic particle dispersion containing inorganic particles and a dispersing medium, and having a pH less than the isoelectric point of the inorganic particles; and a step of adding an alkaline compound to the inorganic particle dispersion in such a manner that the pH does not reach the isoelectric point of the inorganic particles.
