Claim 4:
5. The nanodiamond particle dispersion according to claim 1, wherein the nanodiamond particles having a silane compound bonded to the surface are nanodiamond particles having a structure including the surface modified by a group represented by Formula (1′):, where, in Formula (1′), R4 denotes an alkyl group having from 1 to 3 carbon atoms, R1′ denotes a group represented by Formula (a), R2′ denotes a hydrogen atom, an aliphatic hydrocarbon group having from 1 to 3 carbon atoms, or a group represented by Formula (a), and the atomic bond indicated by the wavy line in the Formula bonds to the surface of the nanodiamond particles:, where, in Formula (a), R4 is the same as described above, R3 and R5 may be the same or different and each denotes a hydrogen atom or an aliphatic hydrocarbon group having from 1 to 3 carbon atoms, m represents an integer of 0 or greater, n represents an integer greater than 0, an atomic bond extending to the left from a silicon atom bonds to an oxygen atom, and an atomic bond indicated by a wavy line bonds to the surface of the nanodiamond particles;
and by a group represented by Formula (2):, where, in Formula (2), R6 denotes an aliphatic hydrocarbon group having 9 or more carbon atoms; R1′ and R2′ are the same as those described above; and the atomic bond indicated by the wavy line in the Formula bonds to the surface of the nanodiamond particles.
