Disclosed is a metal fine particle-dispersing agent for forming a dispersion system of metal fine particles. Specifically disclosed is a metal fine particle-dispersing agent which is composed of a branched and/or linear polymer compound having a dithiocarbamate group as a functional group at an end of the molecule, and a weight average molecular weight of 500-5,000,000. The metal fine particle-dispersing agent may be composed of a branched or linear polymer represented by the following formula (1) or formula (4). |
