Provided are a method for synthesizing a copper-silver alloy that can easily synthesize a copper-silver alloy at a low temperature in a short time, a method for forming a conductive part, and a copper-silver alloy and a conductive part. The present invention includes: an ink preparation step of mixing copper salt particles, an amine-based solvent, and silver salt particles to prepare a copper-silver ink, an application step of applying copper-silver ink to a member to be coated, and generating a crystal particle diameter of 0.2 μm or less from the copper-silver ink A crystal nucleus generation step of at least one of a copper crystal nucleus and a silver crystal nucleus having a crystal particle size of 0.2 μm or less, and a crystal nucleus synthesis step of synthesizing a copper crystal nucleus and the aforementioned silver crystal nucleus. |
