A copper particulate dispersion comprising copper particulates, at least one kind of a dispersion vehicle containing the copper particulates, and at least one kind of dispersant which allows the copper particulates to disperse in the dispersion vehicle, wherein the copper particulates have a center particle diameter of 1 nm or more and less than 100 nm, concentration of the copper particulates is 1% by weight or more and 80% by weight or less based on the copper particulate dispersion, the dispersion vehicle is a polar dispersion vehicle having a boiling point within a range from 150°C to 250°C, the polar dispersion vehicle contains at least one of a protic dispersion vehicle and an aprotic polar dispersion vehicle having a dielectric constant of 30 or more, the protic dispersion vehicle is selected from the group consisting of diethylene glycol monobutyl ether, diethylene glycol monomethyl ether, 2-methylpentane-2,4-diol, ethylene glycol, propylene glycol, 1,5-pentanediol, triethylene glycol, glycerin and sorbitol, the aprotic polar dispersion vehicle is selected from the group consisting of hexamethylphosphoramide, N-methyl pyrrolidone, N-ethyl pyrrolidone, nitrobenzene, N, N-diethylformamide, N, N-dimethylacetamide, furfural, γ-butyrolactone, ethylene sulfite, sulfolane, succinonitrile and ethylene carbonate, the dispersant is a compound having at least one acidic functional group, which has a molecular weight of 200 or more and 100,000 or less, or a salt thereof, concentration of the dispersant is 0.5% by weight or more and 50% by weight or less based on the copper particulate dispersion, and the acidic functional group of the dispersant is selected from the group consisting of a phosphoric acid group, a phosphonic acid group, a sulfonic acid group and a sulfuric acid group. the copper particulates have a center particle diameter of 1 nm or more and less than 100 nm, concentration of the copper particulates is 1% by weight or more and 80% by weight or less based on the copper particulate dispersion, the dispersion vehicle is a polar dispersion vehicle having a boiling point within a range from 150°C to 250°C, the polar dispersion vehicle contains at least one of a protic dispersion vehicle and an aprotic polar dispersion vehicle having a dielectric constant of 30 or more, the protic dispersion vehicle is selected from the group consisting of diethylene glycol monobutyl ether, diethylene glycol monomethyl ether, 2-methylpentane-2,4-diol, ethylene glycol, propylene glycol, 1,5-pentanediol, triethylene glycol, glycerin and sorbitol, the aprotic polar dispersion vehicle is selected from the group consisting of hexamethylphosphoramide, N-methyl pyrrolidone, N-ethyl pyrrolidone, nitrobenzene, N, N-diethylformamide, N, N-dimethylacetamide, furfural, γ-butyrolactone, ethylene sulfite, sulfolane, succinonitrile and ethylene carbonate, the dispersant is a compound having at least one acidic functional group, which has a molecular weight of 200 or more and 100,000 or less, or a salt thereof, concentration of the dispersant is 0.5% by weight or more and 50% by weight or less based on the copper particulate dispersion, and the acidic functional group of the dispersant is selected from the group consisting of a phosphoric acid group, a phosphonic acid group, a sulfonic acid group and a sulfuric acid group.
