A particle material that has high dispersibility in a dispersion medium such as toluene having high hydrophobicity, and a slurry composition in which the particle material is used, are provided for solving the problem. A surface-modified particle material of the present invention includes: a particle material formed of an inorganic material; and a surface treatment agent formed of a silane compound having a first functional group that has any of C, N, and O atoms away over five or more atoms from Si to which an alkoxide is bound, the surface treatment agent allowing surface treatment of the particle material in such an amount that a degree of hydrophobicity becomes not less than 30%. Dispersibility is enhanced also in a dispersion medium having high hydrophobicity in a case where a functional group having a predetermined structure is introduced so as to impart predetermined or higher hydrophobicity.
