Abstract
An organic substance-attached porous inorganic oxide particle including porous inorganic oxide particle and an organic substance attached to the surface of the porous inorganic oxide particle. The organic substance-attached porous inorganic oxide particle satisfies a formula below()/2>1where Cf represents the amount of carbon (atom %) measured by subjecting the surface of the particle to X-ray photoelectron spectroscopy (XPS) after the particle is washed, and Ce represents the amount of carbon (atom %) measured by subjecting the surface of the particle to X-ray photoelectron spectroscopy (XPS) after two-minute surface etching of the particle.
