Abstract
A copper fine particle dispersion including copper nanoparticles A dispersed in the copper fine particle dispersion with a polymer B, and a dispersion medium C. The polymer B contains a constitutional unit derived from a carboxy group-containing monomer (b-1) and a polyalkylene glycol segment-containing monomer (b-2). A content of the polyalkylene glycol segment in the polymer B is not less than 55% by mass and not more than 97% by mass. An acid value of the polymer B is not less than 20 mgKOH/g and not more than 250 mgKOH/g. The dispersion medium C includes at least one compound selected from the group consisting of a (poly)alkylene glycol, a (poly)alkylene glycol derivative, a terpene alcohol, glycerin and a glycerin derivative.
