PROBLEM TO BE SOLVED: To provide a copper particulate dispersion which contains copper particulates with the average particle diameter of 10 nm or less, and a polymer that can be decomposed or can be converted to a compound with a lower molecular weight as a dispersing agent which works as an oxidation-inhibiting agent as well, in a calcination step, and to provide a method for producing the same. SOLUTION: The method for producing the copper particulate dispersion includes the steps of: (a) mixing a hydrazine derivative, a polyhydrazone compound and a copper particulate precursor; and (b) reducing and depositing copper particulates.
