Claim 0:
1. A nanodiamond particle dispersion comprising nanodiamond particles dispersed in an organic solvent,, wherein the nanodiamond particles have a structure including the surface modified by a group represented by Formula (1):, where, in Formula (1), R4 denotes an aliphatic hydrocarbon group having from 1 to 8 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 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 leftward 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,
the organic solvent has an SP value from 8.0 to 14.0 (cal/cm3)1/2, and
the nanodiamond particles are dispersed with a particle diameter (D50) from 2 to 100 nm.
