Disclosed are a metallic nanoparticle cluster ink and a method for forming a conductive metal pattern using the cluster ink. The metallic nanoparticle cluster ink comprises colloidal metallic nanoparticles and a bifunctional compound. The conductive metal pattern is formed by forming a metallic nanoparticle pattern on a substrate using a mold made from PDMS (poly(dimethylsiloxane) polymer as a stamp, and heat-treating the substrate. Micrometer-sized conductive metal patterns can be easily formed on various substrates in a simple and inexpensive manner without the use of costly systems, thereby being very useful in various industrial fields.
