Provided are a method for synthesizing a copper-silver alloy, whereby a copper-silver alloy can easily be synthesized at low temperature and in a short time, a method for forming a conduction part, and a copper-silver alloy and a conduction part. The present invention is provided with an ink preparation step for preparing a copper-silver ink by mixing copper salt particles, an amine-based solvent, and silver salt particles, an application step for applying the copper-silver ink to a member to be coated, a nucleation step for generating copper crystal nuclei having a crystal grain size of 0.2 æm or less and/or silver crystal nuclei having a crystal grain size of 0.2 æm or less from the copper-silver ink, and a crystal nucleus synthesis step for synthesizing the copper crystal nuclei and the silver crystal nuclei. |
