Abstract: An electroless silver plating method which can optionally control the thickness of a silver thin film at a nanometer to micrometer level and the size of silver particles composing the silver thin film at a nanometer level through a very simple process by overcoming non-reproducibility and reaction complexity of a conventional electroless silver plating method is provided. In an electroless silver plating method comprising a step of forming a silver thin film on a matrix by performing a plating process using an electroless plating solution comprising silver ions and a reductant, the electroless silver plating method is characterized in that: the reductant is an aliphatic or aromatic amine compound having 5 or more of pKa; and silver particles of the silver thin film are adjusted to a nanometer to micrometer range by controlling types of amine compounds as the reductant and the relative concentration of the reductant to the silver ions. The electroless silver plating method further comprises a step of patterning the silver thin film as a consequence by partially masking the matrix before performing the plating process.
