Zusammenfassung:	PROBLEM TO BE SOLVED: To form a dense and uniform silver coating film hard to be corroded by external environments and good in adhesion to a substrate at a high silver coating ratio. SOLUTION: In the liquid chemicals for forming the silver coating film composed of a silver soln.contg. ammoniacal silver nitrate and a reduction soln. contg. a reducing agent and strong alkali components, in which they are brought into reaction with to form a silver coating film on a substrate, the silver soln. and/or the reduction soln. is incorporated with at least one or more kinds of additives of the compds.contg. Bi (III), Al (III) and Fe (III) ions.
