PROBLEM TO BE SOLVED: To provide: a method of producing copper particles that can form a conductor film having low volume resistivity; a method of producing a composition for forming a conductor; a method of producing the conductor film using the composition; and an article having the conductor film.;SOLUTION: A method of producing surface-modified copper particles includes: a step of dispersing the copper particles having an aspect ratio of 2.5 to 6 in a dispersion medium and of reducing the copper particles by a reaction system having pH of ≤3 and oxidation-reduction potential of 100-300 mV, thereby obtaining reduced copper particles; and a step of cracking the reduced copper particles to obtain the surface-modified copper particles having an average particle diameter D50 of ≤8.60 μm.;COPYRIGHT: (C)2012,JPO&INPIT
