To provide a method for producing an alumina dispersion liquid in which hydrated alumina powder is well dispersed.
The method is for producing an alumina dispersion liquid containing hydrated alumina powder and an aqueous dispersion medium, which has a supplying process to supply the hydrated alumina powder into an aqueous dispersion medium in dispersing equipment and a dispersing process to disperse the hydrated alumina powder in the aqueous dispersion medium by stirring the aqueous dispersion medium with a stirring means with which the dispersing equipment is equipped. The pH value of the aqueous dispersion medium into which the hydrated alumina is supplied is in a range of 3.0-6.0, and effective consumption power for stirring of the stirring means is in a range of 0.01-0.2 kw/m3.
