Disclosed is a hydrophobic metal oxide particle that does not crush pores of activated carbon and increases the hydrophobicity of activated carbon. Hydrophobic metal oxide particles characterized by being surface-modified with a silicon compound represented by formula (1). As the metal oxide particles, organosilica sol is preferable. R—Si (CH 3 ) n (—X) 3-n (1) Where R is an alkyl group having 1 to 18 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, an alkynyl group having 2 to 3 carbon atoms or an aryl group having 6 to 8 carbon atoms, and X is an alkoxy group having 1 to 3 carbon atoms. , C represents a carbon atom, H represents a hydrogen atom, Si represents a silicon atom, and n represents 0 to 2.
