Abstract
A metatitanic acid particle includes a metal compound having a titanium metal atom and a carbon atom, and being bonded to a surface of the particle via an oxygen atom, wherein an element ratio (C/Ti) between carbon and titanium on the surface is in a range of 0.2 to 1.1 and the metatitanic acid particle has an absorption at a wavelength of each of 450 nm and 750 nm in a visible absorption spectrum.
