Metal nanoparticle dispersion

摘要

According to one embodiment, metal nanoparticle dispersion includes organic solvent, and metal-containing particles dispersed in the organic solvent. The metal-containing particles include first metal nanoparticles and second metal nanoparticles. Each of the first metal nanoparticles has a high-molecular compound on at least part of a surface thereof. Each of the second metal nanoparticles has a low-molecular compound on at least part of a surface thereof. A total amount of the low-molecular compound on all of the second nanoparticles includes an amount of a primary amine as the low-molecular compound.
