Research Abstract	At first, co-deposition. conditions of nanoparticles into electrolessly plated films were studied. Effects of concentration, temperature and pH of the baths were investigated. Size of particles also affected co-deposition characteristics. Next co-deposition mechanism of nanoparticles into electrolessly plated films were studied in detail. It was suggested that nanodiamond particles were co-deposited into the film after adsorption of metal ion onto the surface of the particles. It was found that citrate complex of nickel effectively adsorbed on the surface of nanodiamond particles and the particles co-deposited large amount. Charge of particles in solutions seemed to have no effect on the co-deposition mechanism. No aggregation of the paticles was observed by transmission electron microscope. It was also found that direct observation of nanodiamond particles was impossible.
