Provided is a surface-modified nanodiamond that has high dispersibility in an organic solvent or in a resin and that can maintain the characteristics described above even in a high-temperature environment of 200°C or higher. The surface-modified nanodiamond according to an embodiment of the present invention has a structure in which a surface of a nanodiamond particle is modified by a group represented by Formula (1) below. In the formula, R1 to R4 are the same or different and each represent an aliphatic hydrocarbon group having from 1 to 25 carbons. Note that at least one of R1 to R4 is an aliphatic hydrocarbon group having from 10 to 25 carbons. Furthermore, an atomic bond of the carbon atom in the formula bonds to the surface of the nanodiamond particle.
