Abstract

It is an object of the present invention to provide a nanodispersion liquid of iron oxyhydroxide that is stable and does not contain components derived from auxiliary components. The nanodispersion liquid of iron oxyhydroxide according to the present invention is a nanodispersion liquid in which particles comprising iron oxyhydroxide as a main component and having an average particle diameter d50 of 0.2 μm or less and a d90 of 1 μm or less are dispersed in a solvent. The iron oxyhydroxide is preferably β-iron oxyhydroxide. The nanodispersion liquid of iron oxyhydroxide according to the present invention preferably contains no other components than a substance derived from at least either of an iron compound and a base, a pH adjusting agent, and a solvent.
