PROBLEM TO BE SOLVED: To provide a boron nitride nanotube derivative having good dispersibility in a solvent, its dispersion, and a simple method for producing the boron nitride nanotube derivative. SOLUTION: The boron nitride nanotube derivative is characterized in that≥3 at.% of the surface element composition is oxygen. The boron nitride nanotube derivative may have an average diameter of 0.4 nm to 1μm and an average length of 1-10μm. In the boron nitride nanotube derivative dispersion, the boron nitride nanotube derivative is dispersed in a solvent. The solvent may be at least one selected from the group consisting of water, chloroform, N,N-dimethylacetamide, tetrahydrofuran, N,N-dimethylformamide, acetone, toluene and ethanol.
